00 Inkscape license
11 ================
22
3 Most of Inkscape source code is available under the GNU General Public License,
4 version 2 or later, with the exception of a few files copied from GIMP, which
5 are available under GNU GPL version 3 or later. As such, the complete binaries
6 of Inkscape are currently covered by the terms of GNU GPL version 3 or later.
3 Most Inkscape source code is available under the GNU General Public License, version 2 or later.
74
8 Several standalone libraries contained in Inkscape's source code repository are
9 available under GNU Lesser General Public License or the Mozilla Public License.
5 Notable exceptions are:
6 - some libraries in src/3rdparty and src/2geom (mostly GNU Lesser General Public License or Mozilla Public License).
7 - a few files copied from GIMP, which are available under GNU (L)GPL version 3 or later.
8 - a few files which are dual-licensed, which means that they offer the additional permission to alternatively use them under another license.
109
11 See the files GPL2.txt and GPL3.txt for the full license text.
10 As such, the complete binaries of Inkscape are currently covered by the terms of GNU GPL version 3 or later.

12 License of individual source files
13 ==================================
14
15 The license of each individual inkscape source file can be found in the first few lines after "SPDX-License-Identifier:". The license text of every such license can be found in LICENSES/. Some files are dual-licensed, e.g. "GPL-2.0-or-later OR MPL-1.1", which means you can choose one of these licenses.
16
17 Libraries have their COPYING or LICENSE file in the respective subdirectory.

22 License Compatibility
23 =====================
24
25 Suggested reading for license version compatibility: https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility
26
27 Roughly summarized (I am not a lawyer, this is not legal advice):
28 - You may legally make the following license changes without having to ask anyone:
29 LGPL-2.1-or-later -> GPL-2.0-or-later -> GPL-3.0-or-later
30 LGPL-3.0-or-later -> GPL-3.0-or-later
31 - Due to that, the resulting inkscape must be under GPL-3.0-or-later.
32 - Any license that is not "-or-later" is evil and must not be used in the inkscape project.

1 Version 2, June 1991
2
3 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
4 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
5 Everyone is permitted to copy and distribute verbatim copies
6 of this license document, but changing it is not allowed.
7
8 Preamble
9
10 The licenses for most software are designed to take away your
11 freedom to share and change it. By contrast, the GNU General Public
12 License is intended to guarantee your freedom to share and change free
13 software--to make sure the software is free for all its users. This
14 General Public License applies to most of the Free Software
15 Foundation's software and to any other program whose authors commit to
16 using it. (Some other Free Software Foundation software is covered by
17 the GNU Library General Public License instead.) You can apply it to
18 your programs, too.
19
20 When we speak of free software, we are referring to freedom, not
21 price. Our General Public Licenses are designed to make sure that you
22 have the freedom to distribute copies of free software (and charge for
23 this service if you wish), that you receive source code or can get it
24 if you want it, that you can change the software or use pieces of it
25 in new free programs; and that you know you can do these things.
26
27 To protect your rights, we need to make restrictions that forbid
28 anyone to deny you these rights or to ask you to surrender the rights.
29 These restrictions translate to certain responsibilities for you if you
30 distribute copies of the software, or if you modify it.
31
32 For example, if you distribute copies of such a program, whether
33 gratis or for a fee, you must give the recipients all the rights that
34 you have. You must make sure that they, too, receive or can get the
35 source code. And you must show them these terms so they know their
36 rights.
37
38 We protect your rights with two steps: (1) copyright the software, and
39 (2) offer you this license which gives you legal permission to copy,
40 distribute and/or modify the software.
41
42 Also, for each author's protection and ours, we want to make certain
43 that everyone understands that there is no warranty for this free
44 software. If the software is modified by someone else and passed on, we
45 want its recipients to know that what they have is not the original, so
46 that any problems introduced by others will not reflect on the original
47 authors' reputations.
48
49 Finally, any free program is threatened constantly by software
50 patents. We wish to avoid the danger that redistributors of a free
51 program will individually obtain patent licenses, in effect making the
52 program proprietary. To prevent this, we have made it clear that any
53 patent must be licensed for everyone's free use or not licensed at all.
54
55 The precise terms and conditions for copying, distribution and
56 modification follow.
57
58 GNU GENERAL PUBLIC LICENSE
59 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
60
61 0. This License applies to any program or other work which contains
62 a notice placed by the copyright holder saying it may be distributed
63 under the terms of this General Public License. The "Program", below,
64 refers to any such program or work, and a "work based on the Program"
65 means either the Program or any derivative work under copyright law:
66 that is to say, a work containing the Program or a portion of it,
67 either verbatim or with modifications and/or translated into another
68 language. (Hereinafter, translation is included without limitation in
69 the term "modification".) Each licensee is addressed as "you".
70
71 Activities other than copying, distribution and modification are not
72 covered by this License; they are outside its scope. The act of
73 running the Program is not restricted, and the output from the Program
74 is covered only if its contents constitute a work based on the
75 Program (independent of having been made by running the Program).
76 Whether that is true depends on what the Program does.
77
78 1. You may copy and distribute verbatim copies of the Program's
79 source code as you receive it, in any medium, provided that you
80 conspicuously and appropriately publish on each copy an appropriate
81 copyright notice and disclaimer of warranty; keep intact all the
82 notices that refer to this License and to the absence of any warranty;
83 and give any other recipients of the Program a copy of this License
84 along with the Program.
85
86 You may charge a fee for the physical act of transferring a copy, and
87 you may at your option offer warranty protection in exchange for a fee.
88
89 2. You may modify your copy or copies of the Program or any portion
90 of it, thus forming a work based on the Program, and copy and
91 distribute such modifications or work under the terms of Section 1
92 above, provided that you also meet all of these conditions:
93
94 a) You must cause the modified files to carry prominent notices
95 stating that you changed the files and the date of any change.
96
97 b) You must cause any work that you distribute or publish, that in
98 whole or in part contains or is derived from the Program or any
99 part thereof, to be licensed as a whole at no charge to all third
100 parties under the terms of this License.
101
102 c) If the modified program normally reads commands interactively
103 when run, you must cause it, when started running for such
104 interactive use in the most ordinary way, to print or display an
105 announcement including an appropriate copyright notice and a
106 notice that there is no warranty (or else, saying that you provide
107 a warranty) and that users may redistribute the program under
108 these conditions, and telling the user how to view a copy of this
109 License. (Exception: if the Program itself is interactive but
110 does not normally print such an announcement, your work based on
111 the Program is not required to print an announcement.)
112
113 These requirements apply to the modified work as a whole. If
114 identifiable sections of that work are not derived from the Program,
115 and can be reasonably considered independent and separate works in
116 themselves, then this License, and its terms, do not apply to those
117 sections when you distribute them as separate works. But when you
118 distribute the same sections as part of a whole which is a work based
119 on the Program, the distribution of the whole must be on the terms of
120 this License, whose permissions for other licensees extend to the
121 entire whole, and thus to each and every part regardless of who wrote it.
122
123 Thus, it is not the intent of this section to claim rights or contest
124 your rights to work written entirely by you; rather, the intent is to
125 exercise the right to control the distribution of derivative or
126 collective works based on the Program.
127
128 In addition, mere aggregation of another work not based on the Program
129 with the Program (or with a work based on the Program) on a volume of
130 a storage or distribution medium does not bring the other work under
131 the scope of this License.
132
133 3. You may copy and distribute the Program (or a work based on it,
134 under Section 2) in object code or executable form under the terms of
135 Sections 1 and 2 above provided that you also do one of the following:
136
137 a) Accompany it with the complete corresponding machine-readable
138 source code, which must be distributed under the terms of Sections
139 1 and 2 above on a medium customarily used for software interchange; or,
140
141 b) Accompany it with a written offer, valid for at least three
142 years, to give any third party, for a charge no more than your
143 cost of physically performing source distribution, a complete
144 machine-readable copy of the corresponding source code, to be
145 distributed under the terms of Sections 1 and 2 above on a medium
146 customarily used for software interchange; or,
147
148 c) Accompany it with the information you received as to the offer
149 to distribute corresponding source code. (This alternative is
150 allowed only for noncommercial distribution and only if you
151 received the program in object code or executable form with such
152 an offer, in accord with Subsection b above.)
153
154 The source code for a work means the preferred form of the work for
155 making modifications to it. For an executable work, complete source
156 code means all the source code for all modules it contains, plus any
157 associated interface definition files, plus the scripts used to
158 control compilation and installation of the executable. However, as a
159 special exception, the source code distributed need not include
160 anything that is normally distributed (in either source or binary
161 form) with the major components (compiler, kernel, and so on) of the
162 operating system on which the executable runs, unless that component
163 itself accompanies the executable.
164
165 If distribution of executable or object code is made by offering
166 access to copy from a designated place, then offering equivalent
167 access to copy the source code from the same place counts as
168 distribution of the source code, even though third parties are not
169 compelled to copy the source along with the object code.
170
171 4. You may not copy, modify, sublicense, or distribute the Program
172 except as expressly provided under this License. Any attempt
173 otherwise to copy, modify, sublicense or distribute the Program is
174 void, and will automatically terminate your rights under this License.
175 However, parties who have received copies, or rights, from you under
176 this License will not have their licenses terminated so long as such
177 parties remain in full compliance.
178
179 5. You are not required to accept this License, since you have not
180 signed it. However, nothing else grants you permission to modify or
181 distribute the Program or its derivative works. These actions are
182 prohibited by law if you do not accept this License. Therefore, by
183 modifying or distributing the Program (or any work based on the
184 Program), you indicate your acceptance of this License to do so, and
185 all its terms and conditions for copying, distributing or modifying
186 the Program or works based on it.
187
188 6. Each time you redistribute the Program (or any work based on the
189 Program), the recipient automatically receives a license from the
190 original licensor to copy, distribute or modify the Program subject to
191 these terms and conditions. You may not impose any further
192 restrictions on the recipients' exercise of the rights granted herein.
193 You are not responsible for enforcing compliance by third parties to
194 this License.
195
196 7. If, as a consequence of a court judgment or allegation of patent
197 infringement or for any other reason (not limited to patent issues),
198 conditions are imposed on you (whether by court order, agreement or
199 otherwise) that contradict the conditions of this License, they do not
200 excuse you from the conditions of this License. If you cannot
201 distribute so as to satisfy simultaneously your obligations under this
202 License and any other pertinent obligations, then as a consequence you
203 may not distribute the Program at all. For example, if a patent
204 license would not permit royalty-free redistribution of the Program by
205 all those who receive copies directly or indirectly through you, then
206 the only way you could satisfy both it and this License would be to
207 refrain entirely from distribution of the Program.
208
209 If any portion of this section is held invalid or unenforceable under
210 any particular circumstance, the balance of the section is intended to
211 apply and the section as a whole is intended to apply in other
212 circumstances.
213
214 It is not the purpose of this section to induce you to infringe any
215 patents or other property right claims or to contest validity of any
216 such claims; this section has the sole purpose of protecting the
217 integrity of the free software distribution system, which is
218 implemented by public license practices. Many people have made
219 generous contributions to the wide range of software distributed
220 through that system in reliance on consistent application of that
221 system; it is up to the author/donor to decide if he or she is willing
222 to distribute software through any other system and a licensee cannot
223 impose that choice.
224
225 This section is intended to make thoroughly clear what is believed to
226 be a consequence of the rest of this License.
227
228 8. If the distribution and/or use of the Program is restricted in
229 certain countries either by patents or by copyrighted interfaces, the
230 original copyright holder who places the Program under this License
231 may add an explicit geographical distribution limitation excluding
232 those countries, so that distribution is permitted only in or among
233 countries not thus excluded. In such case, this License incorporates
234 the limitation as if written in the body of this License.
235
236 9. The Free Software Foundation may publish revised and/or new versions
237 of the General Public License from time to time. Such new versions will
238 be similar in spirit to the present version, but may differ in detail to
239 address new problems or concerns.
240
241 Each version is given a distinguishing version number. If the Program
242 specifies a version number of this License which applies to it and "any
243 later version", you have the option of following the terms and conditions
244 either of that version or of any later version published by the Free
245 Software Foundation. If the Program does not specify a version number of
246 this License, you may choose any version ever published by the Free Software
247 Foundation.
248
249 10. If you wish to incorporate parts of the Program into other free
250 programs whose distribution conditions are different, write to the author
251 to ask for permission. For software which is copyrighted by the Free
252 Software Foundation, write to the Free Software Foundation; we sometimes
253 make exceptions for this. Our decision will be guided by the two goals
254 of preserving the free status of all derivatives of our free software and
255 of promoting the sharing and reuse of software generally.
256
257 NO WARRANTY
258
259 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
260 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
261 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
262 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
263 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
264 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
265 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
266 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
267 REPAIR OR CORRECTION.
268
269 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
270 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
271 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
272 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
273 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
274 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
275 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
276 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
277 POSSIBILITY OF SUCH DAMAGES.
278
279 END OF TERMS AND CONDITIONS
280
281 How to Apply These Terms to Your New Programs
282
283 If you develop a new program, and you want it to be of the greatest
284 possible use to the public, the best way to achieve this is to make it
285 free software which everyone can redistribute and change under these terms.
286
287 To do so, attach the following notices to the program. It is safest
288 to attach them to the start of each source file to most effectively
289 convey the exclusion of warranty; and each file should have at least
290 the "copyright" line and a pointer to where the full notice is found.
291
292 <one line to give the program's name and a brief idea of what it does.>
293 Copyright (C) <year> <name of author>
294
295 This program is free software; you can redistribute it and/or modify
296 it under the terms of the GNU General Public License as published by
297 the Free Software Foundation; either version 2 of the License, or
298 (at your option) any later version.
299
300 This program is distributed in the hope that it will be useful,
301 but WITHOUT ANY WARRANTY; without even the implied warranty of
302 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
303 GNU General Public License for more details.
304
305 You should have received a copy of the GNU General Public License
306 along with this program; if not, write to the Free Software
307 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
308
309
310 Also add information on how to contact you by electronic and paper mail.
311
312 If the program is interactive, make it output a short notice like this
313 when it starts in an interactive mode:
314
315 Gnomovision version 69, Copyright (C) year name of author
316 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317 This is free software, and you are welcome to redistribute it
318 under certain conditions; type `show c' for details.
319
320 The hypothetical commands `show w' and `show c' should show the appropriate
321 parts of the General Public License. Of course, the commands you use may
322 be called something other than `show w' and `show c'; they could even be
323 mouse-clicks or menu items--whatever suits your program.
324
325 You should also get your employer (if you work as a programmer) or your
326 school, if any, to sign a "copyright disclaimer" for the program, if
327 necessary. Here is a sample; alter the names:
328
329 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
330 `Gnomovision' (which makes passes at compilers) written by James Hacker.

334
335 This General Public License does not permit incorporating your program into
336 proprietary programs. If your program is a subroutine library, you may
337 consider it more useful to permit linking proprietary applications with the
338 library. If this is what you want to do, use the GNU Library General
339 Public License instead of this License.

7 Preamble
8
9 The GNU General Public License is a free, copyleft license for
10 software and other kinds of works.
11
12 The licenses for most software and other practical works are designed
13 to take away your freedom to share and change the works. By contrast,
14 the GNU General Public License is intended to guarantee your freedom to
15 share and change all versions of a program--to make sure it remains free
16 software for all its users. We, the Free Software Foundation, use the
17 GNU General Public License for most of our software; it applies also to
18 any other work released this way by its authors. You can apply it to
19 your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 them if you wish), that you receive source code or can get it if you
25 want it, that you can change the software or use pieces of it in new
26 free programs, and that you know you can do these things.
27
28 To protect your rights, we need to prevent others from denying you
29 these rights or asking you to surrender the rights. Therefore, you have
30 certain responsibilities if you distribute copies of the software, or if
31 you modify it: responsibilities to respect the freedom of others.
32
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must pass on to the recipients the same
35 freedoms that you received. You must make sure that they, too, receive
36 or can get the source code. And you must show them these terms so they
37 know their rights.
38
39 Developers that use the GNU GPL protect your rights with two steps:
40 (1) assert copyright on the software, and (2) offer you this License
41 giving you legal permission to copy, distribute and/or modify it.
42
43 For the developers' and authors' protection, the GPL clearly explains
44 that there is no warranty for this free software. For both users' and
45 authors' sake, the GPL requires that modified versions be marked as
46 changed, so that their problems will not be attributed erroneously to
47 authors of previous versions.
48
49 Some devices are designed to deny users access to install or run
50 modified versions of the software inside them, although the manufacturer
51 can do so. This is fundamentally incompatible with the aim of
52 protecting users' freedom to change the software. The systematic
53 pattern of such abuse occurs in the area of products for individuals to
54 use, which is precisely where it is most unacceptable. Therefore, we
55 have designed this version of the GPL to prohibit the practice for those
56 products. If such problems arise substantially in other domains, we
57 stand ready to extend this provision to those domains in future versions
58 of the GPL, as needed to protect the freedom of users.
59
60 Finally, every program is threatened constantly by software patents.
61 States should not allow patents to restrict development and use of
62 software on general-purpose computers, but in those that do, we wish to
63 avoid the special danger that patents applied to a free program could
64 make it effectively proprietary. To prevent this, the GPL assures that
65 patents cannot be used to render the program non-free.
66
67 The precise terms and conditions for copying, distribution and
68 modification follow.
69
70 TERMS AND CONDITIONS
71
72 0. Definitions.
73
74 "This License" refers to version 3 of the GNU General Public License.
75
76 "Copyright" also means copyright-like laws that apply to other kinds of
77 works, such as semiconductor masks.
78
79 "The Program" refers to any copyrightable work licensed under this
80 License. Each licensee is addressed as "you". "Licensees" and
81 "recipients" may be individuals or organizations.
82
83 To "modify" a work means to copy from or adapt all or part of the work
84 in a fashion requiring copyright permission, other than the making of an
85 exact copy. The resulting work is called a "modified version" of the
86 earlier work or a work "based on" the earlier work.
87
88 A "covered work" means either the unmodified Program or a work based
89 on the Program.
90
91 To "propagate" a work means to do anything with it that, without
92 permission, would make you directly or secondarily liable for
93 infringement under applicable copyright law, except executing it on a
94 computer or modifying a private copy. Propagation includes copying,
95 distribution (with or without modification), making available to the
96 public, and in some countries other activities as well.
97
98 To "convey" a work means any kind of propagation that enables other
99 parties to make or receive copies. Mere interaction with a user through
100 a computer network, with no transfer of a copy, is not conveying.
101
102 An interactive user interface displays "Appropriate Legal Notices"
103 to the extent that it includes a convenient and prominently visible
104 feature that (1) displays an appropriate copyright notice, and (2)
105 tells the user that there is no warranty for the work (except to the
106 extent that warranties are provided), that licensees may convey the
107 work under this License, and how to view a copy of this License. If
108 the interface presents a list of user commands or options, such as a
109 menu, a prominent item in the list meets this criterion.
110
111 1. Source Code.
112
113 The "source code" for a work means the preferred form of the work
114 for making modifications to it. "Object code" means any non-source
115 form of a work.
116
117 A "Standard Interface" means an interface that either is an official
118 standard defined by a recognized standards body, or, in the case of
119 interfaces specified for a particular programming language, one that
120 is widely used among developers working in that language.
121
122 The "System Libraries" of an executable work include anything, other
123 than the work as a whole, that (a) is included in the normal form of
124 packaging a Major Component, but which is not part of that Major
125 Component, and (b) serves only to enable use of the work with that
126 Major Component, or to implement a Standard Interface for which an
127 implementation is available to the public in source code form. A
128 "Major Component", in this context, means a major essential component
129 (kernel, window system, and so on) of the specific operating system
130 (if any) on which the executable work runs, or a compiler used to
131 produce the work, or an object code interpreter used to run it.
132
133 The "Corresponding Source" for a work in object code form means all
134 the source code needed to generate, install, and (for an executable
135 work) run the object code and to modify the work, including scripts to
136 control those activities. However, it does not include the work's
137 System Libraries, or general-purpose tools or generally available free
138 programs which are used unmodified in performing those activities but
139 which are not part of the work. For example, Corresponding Source
140 includes interface definition files associated with source files for
141 the work, and the source code for shared libraries and dynamically
142 linked subprograms that the work is specifically designed to require,
143 such as by intimate data communication or control flow between those
144 subprograms and other parts of the work.
145
146 The Corresponding Source need not include anything that users
147 can regenerate automatically from other parts of the Corresponding
148 Source.
149
150 The Corresponding Source for a work in source code form is that
151 same work.
152
153 2. Basic Permissions.
154
155 All rights granted under this License are granted for the term of
156 copyright on the Program, and are irrevocable provided the stated
157 conditions are met. This License explicitly affirms your unlimited
158 permission to run the unmodified Program. The output from running a
159 covered work is covered by this License only if the output, given its
160 content, constitutes a covered work. This License acknowledges your
161 rights of fair use or other equivalent, as provided by copyright law.
162
163 You may make, run and propagate covered works that you do not
164 convey, without conditions so long as your license otherwise remains
165 in force. You may convey covered works to others for the sole purpose
166 of having them make modifications exclusively for you, or provide you
167 with facilities for running those works, provided that you comply with
168 the terms of this License in conveying all material for which you do
169 not control copyright. Those thus making or running the covered works
170 for you must do so exclusively on your behalf, under your direction
171 and control, on terms that prohibit them from making any copies of
172 your copyrighted material outside their relationship with you.
173
174 Conveying under any other circumstances is permitted solely under
175 the conditions stated below. Sublicensing is not allowed; section 10
176 makes it unnecessary.
177
178 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
179
180 No covered work shall be deemed part of an effective technological
181 measure under any applicable law fulfilling obligations under article
182 11 of the WIPO copyright treaty adopted on 20 December 1996, or
183 similar laws prohibiting or restricting circumvention of such
184 measures.
185
186 When you convey a covered work, you waive any legal power to forbid
187 circumvention of technological measures to the extent such circumvention
188 is effected by exercising rights under this License with respect to
189 the covered work, and you disclaim any intention to limit operation or
190 modification of the work as a means of enforcing, against the work's
191 users, your or third parties' legal rights to forbid circumvention of
192 technological measures.
193
194 4. Conveying Verbatim Copies.
195
196 You may convey verbatim copies of the Program's source code as you
197 receive it, in any medium, provided that you conspicuously and
198 appropriately publish on each copy an appropriate copyright notice;
199 keep intact all notices stating that this License and any
200 non-permissive terms added in accord with section 7 apply to the code;
201 keep intact all notices of the absence of any warranty; and give all
202 recipients a copy of this License along with the Program.
203
204 You may charge any price or no price for each copy that you convey,
205 and you may offer support or warranty protection for a fee.
206
207 5. Conveying Modified Source Versions.
208
209 You may convey a work based on the Program, or the modifications to
210 produce it from the Program, in the form of source code under the
211 terms of section 4, provided that you also meet all of these conditions:
212
213 a) The work must carry prominent notices stating that you modified
214 it, and giving a relevant date.
215
216 b) The work must carry prominent notices stating that it is
217 released under this License and any conditions added under section
218 7. This requirement modifies the requirement in section 4 to
219 "keep intact all notices".
220
221 c) You must license the entire work, as a whole, under this
222 License to anyone who comes into possession of a copy. This
223 License will therefore apply, along with any applicable section 7
224 additional terms, to the whole of the work, and all its parts,
225 regardless of how they are packaged. This License gives no
226 permission to license the work in any other way, but it does not
227 invalidate such permission if you have separately received it.
228
229 d) If the work has interactive user interfaces, each must display
230 Appropriate Legal Notices; however, if the Program has interactive
231 interfaces that do not display Appropriate Legal Notices, your
232 work need not make them do so.
233
234 A compilation of a covered work with other separate and independent
235 works, which are not by their nature extensions of the covered work,
236 and which are not combined with it such as to form a larger program,
237 in or on a volume of a storage or distribution medium, is called an
238 "aggregate" if the compilation and its resulting copyright are not
239 used to limit the access or legal rights of the compilation's users
240 beyond what the individual works permit. Inclusion of a covered work
241 in an aggregate does not cause this License to apply to the other
242 parts of the aggregate.
243
244 6. Conveying Non-Source Forms.
245
246 You may convey a covered work in object code form under the terms
247 of sections 4 and 5, provided that you also convey the
248 machine-readable Corresponding Source under the terms of this License,
249 in one of these ways:
250
251 a) Convey the object code in, or embodied in, a physical product
252 (including a physical distribution medium), accompanied by the
253 Corresponding Source fixed on a durable physical medium
254 customarily used for software interchange.
255
256 b) Convey the object code in, or embodied in, a physical product
257 (including a physical distribution medium), accompanied by a
258 written offer, valid for at least three years and valid for as
259 long as you offer spare parts or customer support for that product
260 model, to give anyone who possesses the object code either (1) a
261 copy of the Corresponding Source for all the software in the
262 product that is covered by this License, on a durable physical
263 medium customarily used for software interchange, for a price no
264 more than your reasonable cost of physically performing this
265 conveying of source, or (2) access to copy the
266 Corresponding Source from a network server at no charge.
267
268 c) Convey individual copies of the object code with a copy of the
269 written offer to provide the Corresponding Source. This
270 alternative is allowed only occasionally and noncommercially, and
271 only if you received the object code with such an offer, in accord
272 with subsection 6b.
273
274 d) Convey the object code by offering access from a designated
275 place (gratis or for a charge), and offer equivalent access to the
276 Corresponding Source in the same way through the same place at no
277 further charge. You need not require recipients to copy the
278 Corresponding Source along with the object code. If the place to
279 copy the object code is a network server, the Corresponding Source
280 may be on a different server (operated by you or a third party)
281 that supports equivalent copying facilities, provided you maintain
282 clear directions next to the object code saying where to find the
283 Corresponding Source. Regardless of what server hosts the
284 Corresponding Source, you remain obligated to ensure that it is
285 available for as long as needed to satisfy these requirements.
286
287 e) Convey the object code using peer-to-peer transmission, provided
288 you inform other peers where the object code and Corresponding
289 Source of the work are being offered to the general public at no
290 charge under subsection 6d.
291
292 A separable portion of the object code, whose source code is excluded
293 from the Corresponding Source as a System Library, need not be
294 included in conveying the object code work.
295
296 A "User Product" is either (1) a "consumer product", which means any
297 tangible personal property which is normally used for personal, family,
298 or household purposes, or (2) anything designed or sold for incorporation
299 into a dwelling. In determining whether a product is a consumer product,
300 doubtful cases shall be resolved in favor of coverage. For a particular
301 product received by a particular user, "normally used" refers to a
302 typical or common use of that class of product, regardless of the status
303 of the particular user or of the way in which the particular user
304 actually uses, or expects or is expected to use, the product. A product
305 is a consumer product regardless of whether the product has substantial
306 commercial, industrial or non-consumer uses, unless such uses represent
307 the only significant mode of use of the product.
308
309 "Installation Information" for a User Product means any methods,
310 procedures, authorization keys, or other information required to install
311 and execute modified versions of a covered work in that User Product from
312 a modified version of its Corresponding Source. The information must
313 suffice to ensure that the continued functioning of the modified object
314 code is in no case prevented or interfered with solely because
315 modification has been made.
316
317 If you convey an object code work under this section in, or with, or
318 specifically for use in, a User Product, and the conveying occurs as
319 part of a transaction in which the right of possession and use of the
320 User Product is transferred to the recipient in perpetuity or for a
321 fixed term (regardless of how the transaction is characterized), the
322 Corresponding Source conveyed under this section must be accompanied
323 by the Installation Information. But this requirement does not apply
324 if neither you nor any third party retains the ability to install
325 modified object code on the User Product (for example, the work has
326 been installed in ROM).
327
328 The requirement to provide Installation Information does not include a
329 requirement to continue to provide support service, warranty, or updates
330 for a work that has been modified or installed by the recipient, or for
331 the User Product in which it has been modified or installed. Access to a
332 network may be denied when the modification itself materially and
333 adversely affects the operation of the network or violates the rules and
334 protocols for communication across the network.
335
336 Corresponding Source conveyed, and Installation Information provided,
337 in accord with this section must be in a format that is publicly
338 documented (and with an implementation available to the public in
339 source code form), and must require no special password or key for
340 unpacking, reading or copying.
341
342 7. Additional Terms.
343
344 "Additional permissions" are terms that supplement the terms of this
345 License by making exceptions from one or more of its conditions.
346 Additional permissions that are applicable to the entire Program shall
347 be treated as though they were included in this License, to the extent
348 that they are valid under applicable law. If additional permissions
349 apply only to part of the Program, that part may be used separately
350 under those permissions, but the entire Program remains governed by
351 this License without regard to the additional permissions.
352
353 When you convey a copy of a covered work, you may at your option
354 remove any additional permissions from that copy, or from any part of
355 it. (Additional permissions may be written to require their own
356 removal in certain cases when you modify the work.) You may place
357 additional permissions on material, added by you to a covered work,
358 for which you have or can give appropriate copyright permission.
359
360 Notwithstanding any other provision of this License, for material you
361 add to a covered work, you may (if authorized by the copyright holders of
362 that material) supplement the terms of this License with terms:
363
364 a) Disclaiming warranty or limiting liability differently from the
365 terms of sections 15 and 16 of this License; or
366
367 b) Requiring preservation of specified reasonable legal notices or
368 author attributions in that material or in the Appropriate Legal
369 Notices displayed by works containing it; or
370
371 c) Prohibiting misrepresentation of the origin of that material, or
372 requiring that modified versions of such material be marked in
373 reasonable ways as different from the original version; or
374
375 d) Limiting the use for publicity purposes of names of licensors or
376 authors of the material; or
377
378 e) Declining to grant rights under trademark law for use of some
379 trade names, trademarks, or service marks; or
380
381 f) Requiring indemnification of licensors and authors of that
382 material by anyone who conveys the material (or modified versions of
383 it) with contractual assumptions of liability to the recipient, for
384 any liability that these contractual assumptions directly impose on
385 those licensors and authors.
386
387 All other non-permissive additional terms are considered "further
388 restrictions" within the meaning of section 10. If the Program as you
389 received it, or any part of it, contains a notice stating that it is
390 governed by this License along with a term that is a further
391 restriction, you may remove that term. If a license document contains
392 a further restriction but permits relicensing or conveying under this
393 License, you may add to a covered work material governed by the terms
394 of that license document, provided that the further restriction does
395 not survive such relicensing or conveying.
396
397 If you add terms to a covered work in accord with this section, you
398 must place, in the relevant source files, a statement of the
399 additional terms that apply to those files, or a notice indicating
400 where to find the applicable terms.
401
402 Additional terms, permissive or non-permissive, may be stated in the
403 form of a separately written license, or stated as exceptions;
404 the above requirements apply either way.
405
406 8. Termination.
407
408 You may not propagate or modify a covered work except as expressly
409 provided under this License. Any attempt otherwise to propagate or
410 modify it is void, and will automatically terminate your rights under
411 this License (including any patent licenses granted under the third
412 paragraph of section 11).
413
414 However, if you cease all violation of this License, then your
415 license from a particular copyright holder is reinstated (a)
416 provisionally, unless and until the copyright holder explicitly and
417 finally terminates your license, and (b) permanently, if the copyright
418 holder fails to notify you of the violation by some reasonable means
419 prior to 60 days after the cessation.
420
421 Moreover, your license from a particular copyright holder is
422 reinstated permanently if the copyright holder notifies you of the
423 violation by some reasonable means, this is the first time you have
424 received notice of violation of this License (for any work) from that
425 copyright holder, and you cure the violation prior to 30 days after
426 your receipt of the notice.
427
428 Termination of your rights under this section does not terminate the
429 licenses of parties who have received copies or rights from you under
430 this License. If your rights have been terminated and not permanently
431 reinstated, you do not qualify to receive new licenses for the same
432 material under section 10.
433
434 9. Acceptance Not Required for Having Copies.
435
436 You are not required to accept this License in order to receive or
437 run a copy of the Program. Ancillary propagation of a covered work
438 occurring solely as a consequence of using peer-to-peer transmission
439 to receive a copy likewise does not require acceptance. However,
440 nothing other than this License grants you permission to propagate or
441 modify any covered work. These actions infringe copyright if you do
442 not accept this License. Therefore, by modifying or propagating a
443 covered work, you indicate your acceptance of this License to do so.
444
445 10. Automatic Licensing of Downstream Recipients.
446
447 Each time you convey a covered work, the recipient automatically
448 receives a license from the original licensors, to run, modify and
449 propagate that work, subject to this License. You are not responsible
450 for enforcing compliance by third parties with this License.
451
452 An "entity transaction" is a transaction transferring control of an
453 organization, or substantially all assets of one, or subdividing an
454 organization, or merging organizations. If propagation of a covered
455 work results from an entity transaction, each party to that
456 transaction who receives a copy of the work also receives whatever
457 licenses to the work the party's predecessor in interest had or could
458 give under the previous paragraph, plus a right to possession of the
459 Corresponding Source of the work from the predecessor in interest, if
460 the predecessor has it or can get it with reasonable efforts.
461
462 You may not impose any further restrictions on the exercise of the
463 rights granted or affirmed under this License. For example, you may
464 not impose a license fee, royalty, or other charge for exercise of
465 rights granted under this License, and you may not initiate litigation
466 (including a cross-claim or counterclaim in a lawsuit) alleging that
467 any patent claim is infringed by making, using, selling, offering for
468 sale, or importing the Program or any portion of it.
469
470 11. Patents.
471
472 A "contributor" is a copyright holder who authorizes use under this
473 License of the Program or a work on which the Program is based. The
474 work thus licensed is called the contributor's "contributor version".
475
476 A contributor's "essential patent claims" are all patent claims
477 owned or controlled by the contributor, whether already acquired or
478 hereafter acquired, that would be infringed by some manner, permitted
479 by this License, of making, using, or selling its contributor version,
480 but do not include claims that would be infringed only as a
481 consequence of further modification of the contributor version. For
482 purposes of this definition, "control" includes the right to grant
483 patent sublicenses in a manner consistent with the requirements of
484 this License.
485
486 Each contributor grants you a non-exclusive, worldwide, royalty-free
487 patent license under the contributor's essential patent claims, to
488 make, use, sell, offer for sale, import and otherwise run, modify and
489 propagate the contents of its contributor version.
490
491 In the following three paragraphs, a "patent license" is any express
492 agreement or commitment, however denominated, not to enforce a patent
493 (such as an express permission to practice a patent or covenant not to
494 sue for patent infringement). To "grant" such a patent license to a
495 party means to make such an agreement or commitment not to enforce a
496 patent against the party.
497
498 If you convey a covered work, knowingly relying on a patent license,
499 and the Corresponding Source of the work is not available for anyone
500 to copy, free of charge and under the terms of this License, through a
501 publicly available network server or other readily accessible means,
502 then you must either (1) cause the Corresponding Source to be so
503 available, or (2) arrange to deprive yourself of the benefit of the
504 patent license for this particular work, or (3) arrange, in a manner
505 consistent with the requirements of this License, to extend the patent
506 license to downstream recipients. "Knowingly relying" means you have
507 actual knowledge that, but for the patent license, your conveying the
508 covered work in a country, or your recipient's use of the covered work
509 in a country, would infringe one or more identifiable patents in that
510 country that you have reason to believe are valid.
511
512 If, pursuant to or in connection with a single transaction or
513 arrangement, you convey, or propagate by procuring conveyance of, a
514 covered work, and grant a patent license to some of the parties
515 receiving the covered work authorizing them to use, propagate, modify
516 or convey a specific copy of the covered work, then the patent license
517 you grant is automatically extended to all recipients of the covered
518 work and works based on it.
519
520 A patent license is "discriminatory" if it does not include within
521 the scope of its coverage, prohibits the exercise of, or is
522 conditioned on the non-exercise of one or more of the rights that are
523 specifically granted under this License. You may not convey a covered
524 work if you are a party to an arrangement with a third party that is
525 in the business of distributing software, under which you make payment
526 to the third party based on the extent of your activity of conveying
527 the work, and under which the third party grants, to any of the
528 parties who would receive the covered work from you, a discriminatory
529 patent license (a) in connection with copies of the covered work
530 conveyed by you (or copies made from those copies), or (b) primarily
531 for and in connection with specific products or compilations that
532 contain the covered work, unless you entered into that arrangement,
533 or that patent license was granted, prior to 28 March 2007.
534
535 Nothing in this License shall be construed as excluding or limiting
536 any implied license or other defenses to infringement that may
537 otherwise be available to you under applicable patent law.
538
539 12. No Surrender of Others' Freedom.
540
541 If conditions are imposed on you (whether by court order, agreement or
542 otherwise) that contradict the conditions of this License, they do not
543 excuse you from the conditions of this License. If you cannot convey a
544 covered work so as to satisfy simultaneously your obligations under this
545 License and any other pertinent obligations, then as a consequence you may
546 not convey it at all. For example, if you agree to terms that obligate you
547 to collect a royalty for further conveying from those to whom you convey
548 the Program, the only way you could satisfy both those terms and this
549 License would be to refrain entirely from conveying the Program.
550
551 13. Use with the GNU Affero General Public License.
552
553 Notwithstanding any other provision of this License, you have
554 permission to link or combine any covered work with a work licensed
555 under version 3 of the GNU Affero General Public License into a single
556 combined work, and to convey the resulting work. The terms of this
557 License will continue to apply to the part which is the covered work,
558 but the special requirements of the GNU Affero General Public License,
559 section 13, concerning interaction through a network will apply to the
560 combination as such.
561
562 14. Revised Versions of this License.
563
564 The Free Software Foundation may publish revised and/or new versions of
565 the GNU General Public License from time to time. Such new versions will
566 be similar in spirit to the present version, but may differ in detail to
567 address new problems or concerns.
568
569 Each version is given a distinguishing version number. If the
570 Program specifies that a certain numbered version of the GNU General
571 Public License "or any later version" applies to it, you have the
572 option of following the terms and conditions either of that numbered
573 version or of any later version published by the Free Software
574 Foundation. If the Program does not specify a version number of the
575 GNU General Public License, you may choose any version ever published
576 by the Free Software Foundation.
577
578 If the Program specifies that a proxy can decide which future
579 versions of the GNU General Public License can be used, that proxy's
580 public statement of acceptance of a version permanently authorizes you
581 to choose that version for the Program.
582
583 Later license versions may give you additional or different
584 permissions. However, no additional obligations are imposed on any
585 author or copyright holder as a result of your choosing to follow a
586 later version.
587
588 15. Disclaimer of Warranty.
589
590 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
591 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
592 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
593 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
594 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
595 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
596 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
597 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
598

618 copy of the Program in return for a fee.

620 END OF TERMS AND CONDITIONS
621
622 How to Apply These Terms to Your New Programs
623
624 If you develop a new program, and you want it to be of the greatest
625 possible use to the public, the best way to achieve this is to make it
626 free software which everyone can redistribute and change under these terms.
627
628 To do so, attach the following notices to the program. It is safest
629 to attach them to the start of each source file to most effectively
630 state the exclusion of warranty; and each file should have at least
631 the "copyright" line and a pointer to where the full notice is found.
632
633 <one line to give the program's name and a brief idea of what it does.>
634 Copyright (C) <year> <name of author>
635
636 This program is free software: you can redistribute it and/or modify
637 it under the terms of the GNU General Public License as published by
638 the Free Software Foundation, either version 3 of the License, or
639 (at your option) any later version.
640
641 This program is distributed in the hope that it will be useful,
642 but WITHOUT ANY WARRANTY; without even the implied warranty of
643 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
644 GNU General Public License for more details.
645
646 You should have received a copy of the GNU General Public License
647 along with this program. If not, see <http://www.gnu.org/licenses/>.
648
649 Also add information on how to contact you by electronic and paper mail.
650
651 If the program does terminal interaction, make it output a short
652 notice like this when it starts in an interactive mode:
653
654 <program> Copyright (C) <year> <name of author>
655 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
656 This is free software, and you are welcome to redistribute it
657 under certain conditions; type `show c' for details.
658
659 The hypothetical commands `show w' and `show c' should show the appropriate
660 parts of the General Public License. Of course, your program's commands
661 might be different; for a GUI interface, you would use an "about box".
662
663 You should also get your employer (if you work as a programmer) or school,
664 if any, to sign a "copyright disclaimer" for the program, if necessary.
665 For more information on this, and how to apply and follow the GNU GPL, see
666 <http://www.gnu.org/licenses/>.
667
668 The GNU General Public License does not permit incorporating your program
669 into proprietary programs. If your program is a subroutine library, you
670 may consider it more useful to permit linking proprietary applications with
671 the library. If this is what you want to do, use the GNU Lesser General
672 Public License instead of this License. But first, please read
673 <http://www.gnu.org/philosophy/why-not-lgpl.html>.

5 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.
8
9 [This is the first released version of the Lesser GPL. It also counts
10 as the successor of the GNU Library Public License, version 2, hence
11 the version number 2.1.]
12
13 Preamble
14
15 The licenses for most software are designed to take away your
16 freedom to share and change it. By contrast, the GNU General Public
17 Licenses are intended to guarantee your freedom to share and change
18 free software--to make sure the software is free for all its users.
19
20 This license, the Lesser General Public License, applies to some
21 specially designated software packages--typically libraries--of the
22 Free Software Foundation and other authors who decide to use it. You
23 can use it too, but we suggest you first think carefully about whether
24 this license or the ordinary General Public License is the better
25 strategy to use in any particular case, based on the explanations
26 below.
27
28 When we speak of free software, we are referring to freedom of use,
29 not price. Our General Public Licenses are designed to make sure that
30 you have the freedom to distribute copies of free software (and charge
31 for this service if you wish); that you receive source code or can get
32 it if you want it; that you can change the software and use pieces of
33 it in new free programs; and that you are informed that you can do
34 these things.
35
36 To protect your rights, we need to make restrictions that forbid
37 distributors to deny you these rights or to ask you to surrender these
38 rights. These restrictions translate to certain responsibilities for
39 you if you distribute copies of the library or if you modify it.
40
41 For example, if you distribute copies of the library, whether gratis
42 or for a fee, you must give the recipients all the rights that we gave
43 you. You must make sure that they, too, receive or can get the source
44 code. If you link other code with the library, you must provide
45 complete object files to the recipients, so that they can relink them
46 with the library after making changes to the library and recompiling
47 it. And you must show them these terms so they know their rights.
48
49 We protect your rights with a two-step method: (1) we copyright the
50 library, and (2) we offer you this license, which gives you legal
51 permission to copy, distribute and/or modify the library.
52
53 To protect each distributor, we want to make it very clear that
54 there is no warranty for the free library. Also, if the library is
55 modified by someone else and passed on, the recipients should know
56 that what they have is not the original version, so that the original
57 author's reputation will not be affected by problems that might be
58 introduced by others.
59 ^L
60 Finally, software patents pose a constant threat to the existence of
61 any free program. We wish to make sure that a company cannot
62 effectively restrict the users of a free program by obtaining a
63 restrictive license from a patent holder. Therefore, we insist that
64 any patent license obtained for a version of the library must be
65 consistent with the full freedom of use specified in this license.
66
67 Most GNU software, including some libraries, is covered by the
68 ordinary GNU General Public License. This license, the GNU Lesser
69 General Public License, applies to certain designated libraries, and
70 is quite different from the ordinary General Public License. We use
71 this license for certain libraries in order to permit linking those
72 libraries into non-free programs.
73
74 When a program is linked with a library, whether statically or using
75 a shared library, the combination of the two is legally speaking a
76 combined work, a derivative of the original library. The ordinary
77 General Public License therefore permits such linking only if the
78 entire combination fits its criteria of freedom. The Lesser General
79 Public License permits more lax criteria for linking other code with
80 the library.
81
82 We call this license the "Lesser" General Public License because it
83 does Less to protect the user's freedom than the ordinary General
84 Public License. It also provides other free software developers Less
85 of an advantage over competing non-free programs. These disadvantages
86 are the reason we use the ordinary General Public License for many
87 libraries. However, the Lesser license provides advantages in certain
88 special circumstances.
89
90 For example, on rare occasions, there may be a special need to
91 encourage the widest possible use of a certain library, so that it
92 becomes
93 a de-facto standard. To achieve this, non-free programs must be
94 allowed to use the library. A more frequent case is that a free
95 library does the same job as widely used non-free libraries. In this
96 case, there is little to gain by limiting the free library to free
97 software only, so we use the Lesser General Public License.
98
99 In other cases, permission to use a particular library in non-free
100 programs enables a greater number of people to use a large body of
101 free software. For example, permission to use the GNU C Library in
102 non-free programs enables many more people to use the whole GNU
103 operating system, as well as its variant, the GNU/Linux operating
104 system.
105
106 Although the Lesser General Public License is Less protective of the
107 users' freedom, it does ensure that the user of a program that is
108 linked with the Library has the freedom and the wherewithal to run
109 that program using a modified version of the Library.
110
111 The precise terms and conditions for copying, distribution and
112 modification follow. Pay close attention to the difference between a
113 "work based on the library" and a "work that uses the library". The
114 former contains code derived from the library, whereas the latter must
115 be combined with the library in order to run.
116 ^L
117 GNU LESSER GENERAL PUBLIC LICENSE
118 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
119
120 0. This License Agreement applies to any software library or other
121 program which contains a notice placed by the copyright holder or
122 other authorized party saying it may be distributed under the terms of
123 this Lesser General Public License (also called "this License").
124 Each licensee is addressed as "you".
125
126 A "library" means a collection of software functions and/or data
127 prepared so as to be conveniently linked with application programs
128 (which use some of those functions and data) to form executables.
129
130 The "Library", below, refers to any such software library or work
131 which has been distributed under these terms. A "work based on the
132 Library" means either the Library or any derivative work under
133 copyright law: that is to say, a work containing the Library or a
134 portion of it, either verbatim or with modifications and/or translated
135 straightforwardly into another language. (Hereinafter, translation is
136 included without limitation in the term "modification".)
137
138 "Source code" for a work means the preferred form of the work for
139 making modifications to it. For a library, complete source code means
140 all the source code for all modules it contains, plus any associated
141 interface definition files, plus the scripts used to control
142 compilation
143 and installation of the library.
144
145 Activities other than copying, distribution and modification are not
146 covered by this License; they are outside its scope. The act of
147 running a program using the Library is not restricted, and output from
148 such a program is covered only if its contents constitute a work based
149 on the Library (independent of the use of the Library in a tool for
150 writing it). Whether that is true depends on what the Library does
151 and what the program that uses the Library does.
152
153 1. You may copy and distribute verbatim copies of the Library's
154 complete source code as you receive it, in any medium, provided that
155 you conspicuously and appropriately publish on each copy an
156 appropriate copyright notice and disclaimer of warranty; keep intact
157 all the notices that refer to this License and to the absence of any
158 warranty; and distribute a copy of this License along with the
159 Library.
160
161 You may charge a fee for the physical act of transferring a copy,
162 and you may at your option offer warranty protection in exchange for a
163 fee.
164
165 2. You may modify your copy or copies of the Library or any portion
166 of it, thus forming a work based on the Library, and copy and
167 distribute such modifications or work under the terms of Section 1
168 above, provided that you also meet all of these conditions:
169
170 a) The modified work must itself be a software library.
171
172 b) You must cause the files modified to carry prominent notices
173 stating that you changed the files and the date of any change.
174
175 c) You must cause the whole of the work to be licensed at no
176 charge to all third parties under the terms of this License.
177
178 d) If a facility in the modified Library refers to a function or a
179 table of data to be supplied by an application program that uses
180 the facility, other than as an argument passed when the facility
181 is invoked, then you must make a good faith effort to ensure that,
182 in the event an application does not supply such function or
183 table, the facility still operates, and performs whatever part of
184 its purpose remains meaningful.
185
186 (For example, a function in a library to compute square roots has
187 a purpose that is entirely well-defined independent of the
188 application. Therefore, Subsection 2d requires that any
189 application-supplied function or table used by this function must
190 be optional: if the application does not supply it, the square
191 root function must still compute square roots.)
192
193 These requirements apply to the modified work as a whole. If
194 identifiable sections of that work are not derived from the Library,
195 and can be reasonably considered independent and separate works in
196 themselves, then this License, and its terms, do not apply to those
197 sections when you distribute them as separate works. But when you
198 distribute the same sections as part of a whole which is a work based
199 on the Library, the distribution of the whole must be on the terms of
200 this License, whose permissions for other licensees extend to the
201 entire whole, and thus to each and every part regardless of who wrote
202 it.
203
204 Thus, it is not the intent of this section to claim rights or contest
205 your rights to work written entirely by you; rather, the intent is to
206 exercise the right to control the distribution of derivative or
207 collective works based on the Library.
208
209 In addition, mere aggregation of another work not based on the Library
210 with the Library (or with a work based on the Library) on a volume of
211 a storage or distribution medium does not bring the other work under
212 the scope of this License.
213
214 3. You may opt to apply the terms of the ordinary GNU General Public
215 License instead of this License to a given copy of the Library. To do
216 this, you must alter all the notices that refer to this License, so
217 that they refer to the ordinary GNU General Public License, version 2,
218 instead of to this License. (If a newer version than version 2 of the
219 ordinary GNU General Public License has appeared, then you can specify
220 that version instead if you wish.) Do not make any other change in
221 these notices.
222 ^L
223 Once this change is made in a given copy, it is irreversible for
224 that copy, so the ordinary GNU General Public License applies to all
225 subsequent copies and derivative works made from that copy.
226
227 This option is useful when you wish to copy part of the code of
228 the Library into a program that is not a library.
229
230 4. You may copy and distribute the Library (or a portion or
231 derivative of it, under Section 2) in object code or executable form
232 under the terms of Sections 1 and 2 above provided that you accompany
233 it with the complete corresponding machine-readable source code, which
234 must be distributed under the terms of Sections 1 and 2 above on a
235 medium customarily used for software interchange.
236
237 If distribution of object code is made by offering access to copy
238 from a designated place, then offering equivalent access to copy the
239 source code from the same place satisfies the requirement to
240 distribute the source code, even though third parties are not
241 compelled to copy the source along with the object code.
242
243 5. A program that contains no derivative of any portion of the
244 Library, but is designed to work with the Library by being compiled or
245 linked with it, is called a "work that uses the Library". Such a
246 work, in isolation, is not a derivative work of the Library, and
247 therefore falls outside the scope of this License.
248
249 However, linking a "work that uses the Library" with the Library
250 creates an executable that is a derivative of the Library (because it
251 contains portions of the Library), rather than a "work that uses the
252 library". The executable is therefore covered by this License.
253 Section 6 states terms for distribution of such executables.
254
255 When a "work that uses the Library" uses material from a header file
256 that is part of the Library, the object code for the work may be a
257 derivative work of the Library even though the source code is not.
258 Whether this is true is especially significant if the work can be
259 linked without the Library, or if the work is itself a library. The
260 threshold for this to be true is not precisely defined by law.
261
262 If such an object file uses only numerical parameters, data
263 structure layouts and accessors, and small macros and small inline
264 functions (ten lines or less in length), then the use of the object
265 file is unrestricted, regardless of whether it is legally a derivative
266 work. (Executables containing this object code plus portions of the
267 Library will still fall under Section 6.)
268
269 Otherwise, if the work is a derivative of the Library, you may
270 distribute the object code for the work under the terms of Section 6.
271 Any executables containing that work also fall under Section 6,
272 whether or not they are linked directly with the Library itself.
273
274 6. As an exception to the Sections above, you may also combine or
275 link a "work that uses the Library" with the Library to produce a
276 work containing portions of the Library, and distribute that work
277 under terms of your choice, provided that the terms permit
278 modification of the work for the customer's own use and reverse
279 engineering for debugging such modifications.
280
281 You must give prominent notice with each copy of the work that the
282 Library is used in it and that the Library and its use are covered by
283 this License. You must supply a copy of this License. If the work
284 during execution displays copyright notices, you must include the
285 copyright notice for the Library among them, as well as a reference
286 directing the user to the copy of this License. Also, you must do one
287 of these things:
288
289 a) Accompany the work with the complete corresponding
290 machine-readable source code for the Library including whatever
291 changes were used in the work (which must be distributed under
292 Sections 1 and 2 above); and, if the work is an executable linked
293 with the Library, with the complete machine-readable "work that
294 uses the Library", as object code and/or source code, so that the
295 user can modify the Library and then relink to produce a modified
296 executable containing the modified Library. (It is understood
297 that the user who changes the contents of definitions files in the
298 Library will not necessarily be able to recompile the application
299 to use the modified definitions.)
300
301 b) Use a suitable shared library mechanism for linking with the
302 Library. A suitable mechanism is one that (1) uses at run time a
303 copy of the library already present on the user's computer system,
304 rather than copying library functions into the executable, and (2)
305 will operate properly with a modified version of the library, if
306 the user installs one, as long as the modified version is
307 interface-compatible with the version that the work was made with.
308
309 c) Accompany the work with a written offer, valid for at
310 least three years, to give the same user the materials
311 specified in Subsection 6a, above, for a charge no more
312 than the cost of performing this distribution.
313
314 d) If distribution of the work is made by offering access to copy
315 from a designated place, offer equivalent access to copy the above
316 specified materials from the same place.
317
318 e) Verify that the user has already received a copy of these
319 materials or that you have already sent this user a copy.
320
321 For an executable, the required form of the "work that uses the
322 Library" must include any data and utility programs needed for
323 reproducing the executable from it. However, as a special exception,
324 the materials to be distributed need not include anything that is
325 normally distributed (in either source or binary form) with the major
326 components (compiler, kernel, and so on) of the operating system on
327 which the executable runs, unless that component itself accompanies
328 the executable.
329
330 It may happen that this requirement contradicts the license
331 restrictions of other proprietary libraries that do not normally
332 accompany the operating system. Such a contradiction means you cannot
333 use both them and the Library together in an executable that you
334 distribute.
335
336 7. You may place library facilities that are a work based on the
337 Library side-by-side in a single library together with other library
338 facilities not covered by this License, and distribute such a combined
339 library, provided that the separate distribution of the work based on
340 the Library and of the other library facilities is otherwise
341 permitted, and provided that you do these two things:
342
343 a) Accompany the combined library with a copy of the same work
344 based on the Library, uncombined with any other library
345 facilities. This must be distributed under the terms of the
346 Sections above.
347
348 b) Give prominent notice with the combined library of the fact
349 that part of it is a work based on the Library, and explaining
350 where to find the accompanying uncombined form of the same work.
351
352 8. You may not copy, modify, sublicense, link with, or distribute
353 the Library except as expressly provided under this License. Any
354 attempt otherwise to copy, modify, sublicense, link with, or
355 distribute the Library is void, and will automatically terminate your
356 rights under this License. However, parties who have received copies,
357 or rights, from you under this License will not have their licenses
358 terminated so long as such parties remain in full compliance.
359
360 9. You are not required to accept this License, since you have not
361 signed it. However, nothing else grants you permission to modify or
362 distribute the Library or its derivative works. These actions are
363 prohibited by law if you do not accept this License. Therefore, by
364 modifying or distributing the Library (or any work based on the
365 Library), you indicate your acceptance of this License to do so, and
366 all its terms and conditions for copying, distributing or modifying
367 the Library or works based on it.
368
369 10. Each time you redistribute the Library (or any work based on the
370 Library), the recipient automatically receives a license from the
371 original licensor to copy, distribute, link with or modify the Library
372 subject to these terms and conditions. You may not impose any further
373 restrictions on the recipients' exercise of the rights granted herein.
374 You are not responsible for enforcing compliance by third parties with
375 this License.
376
377 11. If, as a consequence of a court judgment or allegation of patent
378 infringement or for any other reason (not limited to patent issues),
379 conditions are imposed on you (whether by court order, agreement or
380 otherwise) that contradict the conditions of this License, they do not
381 excuse you from the conditions of this License. If you cannot
382 distribute so as to satisfy simultaneously your obligations under this
383 License and any other pertinent obligations, then as a consequence you
384 may not distribute the Library at all. For example, if a patent
385 license would not permit royalty-free redistribution of the Library by
386 all those who receive copies directly or indirectly through you, then
387 the only way you could satisfy both it and this License would be to
388 refrain entirely from distribution of the Library.
389
390 If any portion of this section is held invalid or unenforceable under
391 any particular circumstance, the balance of the section is intended to
392 apply, and the section as a whole is intended to apply in other
393 circumstances.
394
395 It is not the purpose of this section to induce you to infringe any
396 patents or other property right claims or to contest validity of any
397 such claims; this section has the sole purpose of protecting the
398 integrity of the free software distribution system which is
399 implemented by public license practices. Many people have made
400 generous contributions to the wide range of software distributed
401 through that system in reliance on consistent application of that
402 system; it is up to the author/donor to decide if he or she is willing
403 to distribute software through any other system and a licensee cannot
404 impose that choice.
405
406 This section is intended to make thoroughly clear what is believed to
407 be a consequence of the rest of this License.
408
409 12. If the distribution and/or use of the Library is restricted in
410 certain countries either by patents or by copyrighted interfaces, the
411 original copyright holder who places the Library under this License
412 may add an explicit geographical distribution limitation excluding those
413 countries, so that distribution is permitted only in or among
414 countries not thus excluded. In such case, this License incorporates
415 the limitation as if written in the body of this License.
416
417 13. The Free Software Foundation may publish revised and/or new
418 versions of the Lesser General Public License from time to time.
419 Such new versions will be similar in spirit to the present version,
420 but may differ in detail to address new problems or concerns.
421
422 Each version is given a distinguishing version number. If the Library
423 specifies a version number of this License which applies to it and
424 "any later version", you have the option of following the terms and
425 conditions either of that version or of any later version published by
426 the Free Software Foundation. If the Library does not specify a
427 license version number, you may choose any version ever published by
428 the Free Software Foundation.
429
430 14. If you wish to incorporate parts of the Library into other free
431 programs whose distribution conditions are incompatible with these,
432 write to the author to ask for permission. For software which is
433 copyrighted by the Free Software Foundation, write to the Free
434 Software Foundation; we sometimes make exceptions for this. Our

457 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
458 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
459 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
460 DAMAGES.

463
464 How to Apply These Terms to Your New Libraries
465
466 If you develop a new library, and you want it to be of the greatest
467 possible use to the public, we recommend making it free software that
468 everyone can redistribute and change. You can do so by permitting
469 redistribution under these terms (or, alternatively, under the terms
470 of the ordinary General Public License).
471
472 To apply these terms, attach the following notices to the library.
473 It is safest to attach them to the start of each source file to most
474 effectively convey the exclusion of warranty; and each file should
475 have at least the "copyright" line and a pointer to where the full
476 notice is found.
477
478
479 <one line to give the library's name and a brief idea of what it
480 does.>

483 This library is free software; you can redistribute it and/or
484 modify it under the terms of the GNU Lesser General Public
485 License as published by the Free Software Foundation; either
486 version 2 of the License, or (at your option) any later version.

488 This library is distributed in the hope that it will be useful,
489 but WITHOUT ANY WARRANTY; without even the implied warranty of

492
493 You should have received a copy of the GNU Lesser General Public
494 License along with this library; if not, write to the Free Software

496
497 Also add information on how to contact you by electronic and paper
498 mail.
499
500 You should also get your employer (if you work as a programmer) or
501 your
502 school, if any, to sign a "copyright disclaimer" for the library, if
503 necessary. Here is a sample; alter the names:

6 of this license document, but changing it is not allowed.

8 Preamble
9
10 The licenses for most software are designed to take away your
11 freedom to share and change it. By contrast, the GNU General Public
12 License is intended to guarantee your freedom to share and change free
13 software--to make sure the software is free for all its users. This
14 General Public License applies to most of the Free Software
15 Foundation's software and to any other program whose authors commit to
16 using it. (Some other Free Software Foundation software is covered by
17 the GNU Library General Public License instead.) You can apply it to
18 your programs, too.
19
20 When we speak of free software, we are referring to freedom, not
21 price. Our General Public Licenses are designed to make sure that you
22 have the freedom to distribute copies of free software (and charge for
23 this service if you wish), that you receive source code or can get it
24 if you want it, that you can change the software or use pieces of it
25 in new free programs; and that you know you can do these things.
26
27 To protect your rights, we need to make restrictions that forbid
28 anyone to deny you these rights or to ask you to surrender the rights.
29 These restrictions translate to certain responsibilities for you if you
30 distribute copies of the software, or if you modify it.
31
32 For example, if you distribute copies of such a program, whether
33 gratis or for a fee, you must give the recipients all the rights that
34 you have. You must make sure that they, too, receive or can get the
35 source code. And you must show them these terms so they know their
36 rights.
37
38 We protect your rights with two steps: (1) copyright the software, and
39 (2) offer you this license which gives you legal permission to copy,
40 distribute and/or modify the software.
41
42 Also, for each author's protection and ours, we want to make certain
43 that everyone understands that there is no warranty for this free
44 software. If the software is modified by someone else and passed on, we
45 want its recipients to know that what they have is not the original, so
46 that any problems introduced by others will not reflect on the original
47 authors' reputations.
48
49 Finally, any free program is threatened constantly by software
50 patents. We wish to avoid the danger that redistributors of a free
51 program will individually obtain patent licenses, in effect making the
52 program proprietary. To prevent this, we have made it clear that any
53 patent must be licensed for everyone's free use or not licensed at all.
54
55 The precise terms and conditions for copying, distribution and
56 modification follow.
57
58 GNU GENERAL PUBLIC LICENSE
59 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
60
61 0. This License applies to any program or other work which contains
62 a notice placed by the copyright holder saying it may be distributed
63 under the terms of this General Public License. The "Program", below,
64 refers to any such program or work, and a "work based on the Program"
65 means either the Program or any derivative work under copyright law:
66 that is to say, a work containing the Program or a portion of it,
67 either verbatim or with modifications and/or translated into another
68 language. (Hereinafter, translation is included without limitation in
69 the term "modification".) Each licensee is addressed as "you".
70
71 Activities other than copying, distribution and modification are not
72 covered by this License; they are outside its scope. The act of
73 running the Program is not restricted, and the output from the Program
74 is covered only if its contents constitute a work based on the
75 Program (independent of having been made by running the Program).
76 Whether that is true depends on what the Program does.
77
78 1. You may copy and distribute verbatim copies of the Program's
79 source code as you receive it, in any medium, provided that you
80 conspicuously and appropriately publish on each copy an appropriate
81 copyright notice and disclaimer of warranty; keep intact all the
82 notices that refer to this License and to the absence of any warranty;
83 and give any other recipients of the Program a copy of this License
84 along with the Program.
85
86 You may charge a fee for the physical act of transferring a copy, and
87 you may at your option offer warranty protection in exchange for a fee.
88
89 2. You may modify your copy or copies of the Program or any portion
90 of it, thus forming a work based on the Program, and copy and
91 distribute such modifications or work under the terms of Section 1
92 above, provided that you also meet all of these conditions:
93
94 a) You must cause the modified files to carry prominent notices
95 stating that you changed the files and the date of any change.
96
97 b) You must cause any work that you distribute or publish, that in
98 whole or in part contains or is derived from the Program or any
99 part thereof, to be licensed as a whole at no charge to all third
100 parties under the terms of this License.
101
102 c) If the modified program normally reads commands interactively
103 when run, you must cause it, when started running for such
104 interactive use in the most ordinary way, to print or display an
105 announcement including an appropriate copyright notice and a
106 notice that there is no warranty (or else, saying that you provide
107 a warranty) and that users may redistribute the program under
108 these conditions, and telling the user how to view a copy of this
109 License. (Exception: if the Program itself is interactive but
110 does not normally print such an announcement, your work based on
111 the Program is not required to print an announcement.)
112
113 These requirements apply to the modified work as a whole. If
114 identifiable sections of that work are not derived from the Program,
115 and can be reasonably considered independent and separate works in
116 themselves, then this License, and its terms, do not apply to those
117 sections when you distribute them as separate works. But when you
118 distribute the same sections as part of a whole which is a work based
119 on the Program, the distribution of the whole must be on the terms of
120 this License, whose permissions for other licensees extend to the
121 entire whole, and thus to each and every part regardless of who wrote it.
122
123 Thus, it is not the intent of this section to claim rights or contest
124 your rights to work written entirely by you; rather, the intent is to
125 exercise the right to control the distribution of derivative or
126 collective works based on the Program.
127
128 In addition, mere aggregation of another work not based on the Program
129 with the Program (or with a work based on the Program) on a volume of
130 a storage or distribution medium does not bring the other work under
131 the scope of this License.
132
133 3. You may copy and distribute the Program (or a work based on it,
134 under Section 2) in object code or executable form under the terms of
135 Sections 1 and 2 above provided that you also do one of the following:
136
137 a) Accompany it with the complete corresponding machine-readable
138 source code, which must be distributed under the terms of Sections
139 1 and 2 above on a medium customarily used for software interchange; or,
140
141 b) Accompany it with a written offer, valid for at least three
142 years, to give any third party, for a charge no more than your
143 cost of physically performing source distribution, a complete
144 machine-readable copy of the corresponding source code, to be
145 distributed under the terms of Sections 1 and 2 above on a medium
146 customarily used for software interchange; or,
147
148 c) Accompany it with the information you received as to the offer
149 to distribute corresponding source code. (This alternative is
150 allowed only for noncommercial distribution and only if you
151 received the program in object code or executable form with such
152 an offer, in accord with Subsection b above.)
153
154 The source code for a work means the preferred form of the work for
155 making modifications to it. For an executable work, complete source
156 code means all the source code for all modules it contains, plus any
157 associated interface definition files, plus the scripts used to
158 control compilation and installation of the executable. However, as a
159 special exception, the source code distributed need not include
160 anything that is normally distributed (in either source or binary
161 form) with the major components (compiler, kernel, and so on) of the
162 operating system on which the executable runs, unless that component
163 itself accompanies the executable.
164
165 If distribution of executable or object code is made by offering
166 access to copy from a designated place, then offering equivalent
167 access to copy the source code from the same place counts as
168 distribution of the source code, even though third parties are not
169 compelled to copy the source along with the object code.
170
171 4. You may not copy, modify, sublicense, or distribute the Program
172 except as expressly provided under this License. Any attempt
173 otherwise to copy, modify, sublicense or distribute the Program is
174 void, and will automatically terminate your rights under this License.
175 However, parties who have received copies, or rights, from you under
176 this License will not have their licenses terminated so long as such
177 parties remain in full compliance.
178
179 5. You are not required to accept this License, since you have not
180 signed it. However, nothing else grants you permission to modify or
181 distribute the Program or its derivative works. These actions are
182 prohibited by law if you do not accept this License. Therefore, by
183 modifying or distributing the Program (or any work based on the
184 Program), you indicate your acceptance of this License to do so, and
185 all its terms and conditions for copying, distributing or modifying
186 the Program or works based on it.
187
188 6. Each time you redistribute the Program (or any work based on the
189 Program), the recipient automatically receives a license from the
190 original licensor to copy, distribute or modify the Program subject to
191 these terms and conditions. You may not impose any further
192 restrictions on the recipients' exercise of the rights granted herein.
193 You are not responsible for enforcing compliance by third parties to
194 this License.
195
196 7. If, as a consequence of a court judgment or allegation of patent
197 infringement or for any other reason (not limited to patent issues),
198 conditions are imposed on you (whether by court order, agreement or
199 otherwise) that contradict the conditions of this License, they do not
200 excuse you from the conditions of this License. If you cannot
201 distribute so as to satisfy simultaneously your obligations under this
202 License and any other pertinent obligations, then as a consequence you
203 may not distribute the Program at all. For example, if a patent
204 license would not permit royalty-free redistribution of the Program by
205 all those who receive copies directly or indirectly through you, then
206 the only way you could satisfy both it and this License would be to
207 refrain entirely from distribution of the Program.
208
209 If any portion of this section is held invalid or unenforceable under
210 any particular circumstance, the balance of the section is intended to
211 apply and the section as a whole is intended to apply in other
212 circumstances.
213
214 It is not the purpose of this section to induce you to infringe any
215 patents or other property right claims or to contest validity of any
216 such claims; this section has the sole purpose of protecting the
217 integrity of the free software distribution system, which is
218 implemented by public license practices. Many people have made
219 generous contributions to the wide range of software distributed
220 through that system in reliance on consistent application of that
221 system; it is up to the author/donor to decide if he or she is willing
222 to distribute software through any other system and a licensee cannot
223 impose that choice.
224
225 This section is intended to make thoroughly clear what is believed to
226 be a consequence of the rest of this License.
227
228 8. If the distribution and/or use of the Program is restricted in
229 certain countries either by patents or by copyrighted interfaces, the
230 original copyright holder who places the Program under this License
231 may add an explicit geographical distribution limitation excluding
232 those countries, so that distribution is permitted only in or among
233 countries not thus excluded. In such case, this License incorporates
234 the limitation as if written in the body of this License.
235
236 9. The Free Software Foundation may publish revised and/or new versions
237 of the General Public License from time to time. Such new versions will
238 be similar in spirit to the present version, but may differ in detail to
239 address new problems or concerns.
240
241 Each version is given a distinguishing version number. If the Program
242 specifies a version number of this License which applies to it and "any
243 later version", you have the option of following the terms and conditions
244 either of that version or of any later version published by the Free
245 Software Foundation. If the Program does not specify a version number of
246 this License, you may choose any version ever published by the Free Software
247 Foundation.
248
249 10. If you wish to incorporate parts of the Program into other free
250 programs whose distribution conditions are different, write to the author
251 to ask for permission. For software which is copyrighted by the Free
252 Software Foundation, write to the Free Software Foundation; we sometimes
253 make exceptions for this. Our decision will be guided by the two goals
254 of preserving the free status of all derivatives of our free software and
255 of promoting the sharing and reuse of software generally.
256
257 NO WARRANTY
258
259 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
260 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
261 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
262 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
263 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
264 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
265 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
266 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
267 REPAIR OR CORRECTION.
268
269 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
270 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
271 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
272 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
273 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
274 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
275 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
276 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
277 POSSIBILITY OF SUCH DAMAGES.
278
279 END OF TERMS AND CONDITIONS
280
281 How to Apply These Terms to Your New Programs
282
283 If you develop a new program, and you want it to be of the greatest
284 possible use to the public, the best way to achieve this is to make it
285 free software which everyone can redistribute and change under these terms.
286
287 To do so, attach the following notices to the program. It is safest
288 to attach them to the start of each source file to most effectively
289 convey the exclusion of warranty; and each file should have at least
290 the "copyright" line and a pointer to where the full notice is found.
291

293 Copyright (C) <year> <name of author>
294
295 This program is free software; you can redistribute it and/or modify
296 it under the terms of the GNU General Public License as published by
297 the Free Software Foundation; either version 2 of the License, or
298 (at your option) any later version.
299
300 This program is distributed in the hope that it will be useful,
301 but WITHOUT ANY WARRANTY; without even the implied warranty of
302 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
303 GNU General Public License for more details.
304
305 You should have received a copy of the GNU General Public License
306 along with this program; if not, write to the Free Software
307 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
308
309
310 Also add information on how to contact you by electronic and paper mail.
311
312 If the program is interactive, make it output a short notice like this
313 when it starts in an interactive mode:
314
315 Gnomovision version 69, Copyright (C) year name of author
316 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317 This is free software, and you are welcome to redistribute it
318 under certain conditions; type `show c' for details.
319
320 The hypothetical commands `show w' and `show c' should show the appropriate
321 parts of the General Public License. Of course, the commands you use may
322 be called something other than `show w' and `show c'; they could even be
323 mouse-clicks or menu items--whatever suits your program.
324
325 You should also get your employer (if you work as a programmer) or your
326 school, if any, to sign a "copyright disclaimer" for the program, if
327 necessary. Here is a sample; alter the names:
328
329 Yoyodyne, Inc., hereby disclaims all copyright interest in the program

335 This General Public License does not permit incorporating your program into
336 proprietary programs. If your program is a subroutine library, you may
337 consider it more useful to permit linking proprietary applications with the
338 library. If this is what you want to do, use the GNU Library General
339 Public License instead of this License.

7 Preamble
8
9 The GNU General Public License is a free, copyleft license for
10 software and other kinds of works.
11
12 The licenses for most software and other practical works are designed
13 to take away your freedom to share and change the works. By contrast,
14 the GNU General Public License is intended to guarantee your freedom to
15 share and change all versions of a program--to make sure it remains free
16 software for all its users. We, the Free Software Foundation, use the
17 GNU General Public License for most of our software; it applies also to
18 any other work released this way by its authors. You can apply it to
19 your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 them if you wish), that you receive source code or can get it if you
25 want it, that you can change the software or use pieces of it in new
26 free programs, and that you know you can do these things.
27
28 To protect your rights, we need to prevent others from denying you
29 these rights or asking you to surrender the rights. Therefore, you have
30 certain responsibilities if you distribute copies of the software, or if
31 you modify it: responsibilities to respect the freedom of others.
32
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must pass on to the recipients the same
35 freedoms that you received. You must make sure that they, too, receive
36 or can get the source code. And you must show them these terms so they
37 know their rights.
38
39 Developers that use the GNU GPL protect your rights with two steps:
40 (1) assert copyright on the software, and (2) offer you this License
41 giving you legal permission to copy, distribute and/or modify it.
42
43 For the developers' and authors' protection, the GPL clearly explains
44 that there is no warranty for this free software. For both users' and
45 authors' sake, the GPL requires that modified versions be marked as
46 changed, so that their problems will not be attributed erroneously to
47 authors of previous versions.
48
49 Some devices are designed to deny users access to install or run
50 modified versions of the software inside them, although the manufacturer
51 can do so. This is fundamentally incompatible with the aim of
52 protecting users' freedom to change the software. The systematic
53 pattern of such abuse occurs in the area of products for individuals to
54 use, which is precisely where it is most unacceptable. Therefore, we
55 have designed this version of the GPL to prohibit the practice for those
56 products. If such problems arise substantially in other domains, we
57 stand ready to extend this provision to those domains in future versions
58 of the GPL, as needed to protect the freedom of users.
59
60 Finally, every program is threatened constantly by software patents.
61 States should not allow patents to restrict development and use of
62 software on general-purpose computers, but in those that do, we wish to
63 avoid the special danger that patents applied to a free program could
64 make it effectively proprietary. To prevent this, the GPL assures that
65 patents cannot be used to render the program non-free.
66
67 The precise terms and conditions for copying, distribution and
68 modification follow.

73
74 "This License" refers to version 3 of the GNU General Public License.
75
76 "Copyright" also means copyright-like laws that apply to other kinds of
77 works, such as semiconductor masks.

79 "The Program" refers to any copyrightable work licensed under this
80 License. Each licensee is addressed as "you". "Licensees" and
81 "recipients" may be individuals or organizations.
82
83 To "modify" a work means to copy from or adapt all or part of the work
84 in a fashion requiring copyright permission, other than the making of an
85 exact copy. The resulting work is called a "modified version" of the
86 earlier work or a work "based on" the earlier work.
87
88 A "covered work" means either the unmodified Program or a work based
89 on the Program.
90
91 To "propagate" a work means to do anything with it that, without
92 permission, would make you directly or secondarily liable for
93 infringement under applicable copyright law, except executing it on a
94 computer or modifying a private copy. Propagation includes copying,
95 distribution (with or without modification), making available to the
96 public, and in some countries other activities as well.
97
98 To "convey" a work means any kind of propagation that enables other
99 parties to make or receive copies. Mere interaction with a user through
100 a computer network, with no transfer of a copy, is not conveying.
101
102 An interactive user interface displays "Appropriate Legal Notices"
103 to the extent that it includes a convenient and prominently visible
104 feature that (1) displays an appropriate copyright notice, and (2)
105 tells the user that there is no warranty for the work (except to the
106 extent that warranties are provided), that licensees may convey the
107 work under this License, and how to view a copy of this License. If
108 the interface presents a list of user commands or options, such as a
109 menu, a prominent item in the list meets this criterion.
110
111 1. Source Code.
112
113 The "source code" for a work means the preferred form of the work
114 for making modifications to it. "Object code" means any non-source
115 form of a work.
116
117 A "Standard Interface" means an interface that either is an official
118 standard defined by a recognized standards body, or, in the case of
119 interfaces specified for a particular programming language, one that
120 is widely used among developers working in that language.
121
122 The "System Libraries" of an executable work include anything, other
123 than the work as a whole, that (a) is included in the normal form of
124 packaging a Major Component, but which is not part of that Major
125 Component, and (b) serves only to enable use of the work with that
126 Major Component, or to implement a Standard Interface for which an
127 implementation is available to the public in source code form. A
128 "Major Component", in this context, means a major essential component
129 (kernel, window system, and so on) of the specific operating system
130 (if any) on which the executable work runs, or a compiler used to
131 produce the work, or an object code interpreter used to run it.
132
133 The "Corresponding Source" for a work in object code form means all
134 the source code needed to generate, install, and (for an executable
135 work) run the object code and to modify the work, including scripts to
136 control those activities. However, it does not include the work's
137 System Libraries, or general-purpose tools or generally available free
138 programs which are used unmodified in performing those activities but
139 which are not part of the work. For example, Corresponding Source
140 includes interface definition files associated with source files for
141 the work, and the source code for shared libraries and dynamically
142 linked subprograms that the work is specifically designed to require,
143 such as by intimate data communication or control flow between those
144 subprograms and other parts of the work.
145
146 The Corresponding Source need not include anything that users
147 can regenerate automatically from other parts of the Corresponding
148 Source.
149
150 The Corresponding Source for a work in source code form is that
151 same work.
152
153 2. Basic Permissions.
154
155 All rights granted under this License are granted for the term of
156 copyright on the Program, and are irrevocable provided the stated
157 conditions are met. This License explicitly affirms your unlimited
158 permission to run the unmodified Program. The output from running a
159 covered work is covered by this License only if the output, given its
160 content, constitutes a covered work. This License acknowledges your
161 rights of fair use or other equivalent, as provided by copyright law.
162
163 You may make, run and propagate covered works that you do not
164 convey, without conditions so long as your license otherwise remains
165 in force. You may convey covered works to others for the sole purpose
166 of having them make modifications exclusively for you, or provide you
167 with facilities for running those works, provided that you comply with
168 the terms of this License in conveying all material for which you do
169 not control copyright. Those thus making or running the covered works
170 for you must do so exclusively on your behalf, under your direction
171 and control, on terms that prohibit them from making any copies of
172 your copyrighted material outside their relationship with you.
173
174 Conveying under any other circumstances is permitted solely under
175 the conditions stated below. Sublicensing is not allowed; section 10
176 makes it unnecessary.
177
178 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
179
180 No covered work shall be deemed part of an effective technological
181 measure under any applicable law fulfilling obligations under article
182 11 of the WIPO copyright treaty adopted on 20 December 1996, or
183 similar laws prohibiting or restricting circumvention of such
184 measures.
185
186 When you convey a covered work, you waive any legal power to forbid
187 circumvention of technological measures to the extent such circumvention
188 is effected by exercising rights under this License with respect to
189 the covered work, and you disclaim any intention to limit operation or
190 modification of the work as a means of enforcing, against the work's
191 users, your or third parties' legal rights to forbid circumvention of
192 technological measures.
193
194 4. Conveying Verbatim Copies.
195
196 You may convey verbatim copies of the Program's source code as you
197 receive it, in any medium, provided that you conspicuously and
198 appropriately publish on each copy an appropriate copyright notice;
199 keep intact all notices stating that this License and any
200 non-permissive terms added in accord with section 7 apply to the code;
201 keep intact all notices of the absence of any warranty; and give all
202 recipients a copy of this License along with the Program.
203
204 You may charge any price or no price for each copy that you convey,
205 and you may offer support or warranty protection for a fee.
206
207 5. Conveying Modified Source Versions.
208
209 You may convey a work based on the Program, or the modifications to
210 produce it from the Program, in the form of source code under the
211 terms of section 4, provided that you also meet all of these conditions:
212
213 a) The work must carry prominent notices stating that you modified
214 it, and giving a relevant date.
215
216 b) The work must carry prominent notices stating that it is
217 released under this License and any conditions added under section
218 7. This requirement modifies the requirement in section 4 to
219 "keep intact all notices".
220
221 c) You must license the entire work, as a whole, under this
222 License to anyone who comes into possession of a copy. This
223 License will therefore apply, along with any applicable section 7
224 additional terms, to the whole of the work, and all its parts,
225 regardless of how they are packaged. This License gives no
226 permission to license the work in any other way, but it does not
227 invalidate such permission if you have separately received it.
228
229 d) If the work has interactive user interfaces, each must display
230 Appropriate Legal Notices; however, if the Program has interactive
231 interfaces that do not display Appropriate Legal Notices, your
232 work need not make them do so.
233
234 A compilation of a covered work with other separate and independent
235 works, which are not by their nature extensions of the covered work,
236 and which are not combined with it such as to form a larger program,
237 in or on a volume of a storage or distribution medium, is called an
238 "aggregate" if the compilation and its resulting copyright are not
239 used to limit the access or legal rights of the compilation's users
240 beyond what the individual works permit. Inclusion of a covered work
241 in an aggregate does not cause this License to apply to the other
242 parts of the aggregate.
243
244 6. Conveying Non-Source Forms.
245
246 You may convey a covered work in object code form under the terms
247 of sections 4 and 5, provided that you also convey the
248 machine-readable Corresponding Source under the terms of this License,
249 in one of these ways:
250
251 a) Convey the object code in, or embodied in, a physical product
252 (including a physical distribution medium), accompanied by the
253 Corresponding Source fixed on a durable physical medium
254 customarily used for software interchange.
255
256 b) Convey the object code in, or embodied in, a physical product
257 (including a physical distribution medium), accompanied by a
258 written offer, valid for at least three years and valid for as
259 long as you offer spare parts or customer support for that product
260 model, to give anyone who possesses the object code either (1) a
261 copy of the Corresponding Source for all the software in the
262 product that is covered by this License, on a durable physical
263 medium customarily used for software interchange, for a price no
264 more than your reasonable cost of physically performing this
265 conveying of source, or (2) access to copy the
266 Corresponding Source from a network server at no charge.
267
268 c) Convey individual copies of the object code with a copy of the
269 written offer to provide the Corresponding Source. This
270 alternative is allowed only occasionally and noncommercially, and
271 only if you received the object code with such an offer, in accord
272 with subsection 6b.
273
274 d) Convey the object code by offering access from a designated
275 place (gratis or for a charge), and offer equivalent access to the
276 Corresponding Source in the same way through the same place at no
277 further charge. You need not require recipients to copy the
278 Corresponding Source along with the object code. If the place to
279 copy the object code is a network server, the Corresponding Source
280 may be on a different server (operated by you or a third party)
281 that supports equivalent copying facilities, provided you maintain
282 clear directions next to the object code saying where to find the
283 Corresponding Source. Regardless of what server hosts the
284 Corresponding Source, you remain obligated to ensure that it is
285 available for as long as needed to satisfy these requirements.
286
287 e) Convey the object code using peer-to-peer transmission, provided
288 you inform other peers where the object code and Corresponding
289 Source of the work are being offered to the general public at no
290 charge under subsection 6d.
291
292 A separable portion of the object code, whose source code is excluded
293 from the Corresponding Source as a System Library, need not be
294 included in conveying the object code work.
295
296 A "User Product" is either (1) a "consumer product", which means any
297 tangible personal property which is normally used for personal, family,
298 or household purposes, or (2) anything designed or sold for incorporation
299 into a dwelling. In determining whether a product is a consumer product,
300 doubtful cases shall be resolved in favor of coverage. For a particular
301 product received by a particular user, "normally used" refers to a
302 typical or common use of that class of product, regardless of the status
303 of the particular user or of the way in which the particular user
304 actually uses, or expects or is expected to use, the product. A product
305 is a consumer product regardless of whether the product has substantial
306 commercial, industrial or non-consumer uses, unless such uses represent
307 the only significant mode of use of the product.
308
309 "Installation Information" for a User Product means any methods,
310 procedures, authorization keys, or other information required to install
311 and execute modified versions of a covered work in that User Product from
312 a modified version of its Corresponding Source. The information must
313 suffice to ensure that the continued functioning of the modified object
314 code is in no case prevented or interfered with solely because
315 modification has been made.
316
317 If you convey an object code work under this section in, or with, or
318 specifically for use in, a User Product, and the conveying occurs as
319 part of a transaction in which the right of possession and use of the
320 User Product is transferred to the recipient in perpetuity or for a
321 fixed term (regardless of how the transaction is characterized), the
322 Corresponding Source conveyed under this section must be accompanied
323 by the Installation Information. But this requirement does not apply
324 if neither you nor any third party retains the ability to install
325 modified object code on the User Product (for example, the work has
326 been installed in ROM).
327
328 The requirement to provide Installation Information does not include a
329 requirement to continue to provide support service, warranty, or updates
330 for a work that has been modified or installed by the recipient, or for
331 the User Product in which it has been modified or installed. Access to a
332 network may be denied when the modification itself materially and
333 adversely affects the operation of the network or violates the rules and
334 protocols for communication across the network.
335
336 Corresponding Source conveyed, and Installation Information provided,
337 in accord with this section must be in a format that is publicly
338 documented (and with an implementation available to the public in
339 source code form), and must require no special password or key for
340 unpacking, reading or copying.
341
342 7. Additional Terms.
343
344 "Additional permissions" are terms that supplement the terms of this
345 License by making exceptions from one or more of its conditions.
346 Additional permissions that are applicable to the entire Program shall
347 be treated as though they were included in this License, to the extent
348 that they are valid under applicable law. If additional permissions
349 apply only to part of the Program, that part may be used separately
350 under those permissions, but the entire Program remains governed by
351 this License without regard to the additional permissions.
352
353 When you convey a copy of a covered work, you may at your option
354 remove any additional permissions from that copy, or from any part of
355 it. (Additional permissions may be written to require their own
356 removal in certain cases when you modify the work.) You may place
357 additional permissions on material, added by you to a covered work,
358 for which you have or can give appropriate copyright permission.
359
360 Notwithstanding any other provision of this License, for material you
361 add to a covered work, you may (if authorized by the copyright holders of
362 that material) supplement the terms of this License with terms:
363
364 a) Disclaiming warranty or limiting liability differently from the
365 terms of sections 15 and 16 of this License; or
366
367 b) Requiring preservation of specified reasonable legal notices or
368 author attributions in that material or in the Appropriate Legal
369 Notices displayed by works containing it; or
370
371 c) Prohibiting misrepresentation of the origin of that material, or
372 requiring that modified versions of such material be marked in
373 reasonable ways as different from the original version; or
374
375 d) Limiting the use for publicity purposes of names of licensors or
376 authors of the material; or
377
378 e) Declining to grant rights under trademark law for use of some
379 trade names, trademarks, or service marks; or
380
381 f) Requiring indemnification of licensors and authors of that
382 material by anyone who conveys the material (or modified versions of
383 it) with contractual assumptions of liability to the recipient, for
384 any liability that these contractual assumptions directly impose on
385 those licensors and authors.
386
387 All other non-permissive additional terms are considered "further
388 restrictions" within the meaning of section 10. If the Program as you
389 received it, or any part of it, contains a notice stating that it is
390 governed by this License along with a term that is a further
391 restriction, you may remove that term. If a license document contains
392 a further restriction but permits relicensing or conveying under this
393 License, you may add to a covered work material governed by the terms
394 of that license document, provided that the further restriction does
395 not survive such relicensing or conveying.
396
397 If you add terms to a covered work in accord with this section, you
398 must place, in the relevant source files, a statement of the
399 additional terms that apply to those files, or a notice indicating
400 where to find the applicable terms.
401
402 Additional terms, permissive or non-permissive, may be stated in the
403 form of a separately written license, or stated as exceptions;
404 the above requirements apply either way.
405
406 8. Termination.
407
408 You may not propagate or modify a covered work except as expressly
409 provided under this License. Any attempt otherwise to propagate or
410 modify it is void, and will automatically terminate your rights under
411 this License (including any patent licenses granted under the third
412 paragraph of section 11).
413
414 However, if you cease all violation of this License, then your
415 license from a particular copyright holder is reinstated (a)
416 provisionally, unless and until the copyright holder explicitly and
417 finally terminates your license, and (b) permanently, if the copyright
418 holder fails to notify you of the violation by some reasonable means
419 prior to 60 days after the cessation.
420
421 Moreover, your license from a particular copyright holder is
422 reinstated permanently if the copyright holder notifies you of the
423 violation by some reasonable means, this is the first time you have
424 received notice of violation of this License (for any work) from that
425 copyright holder, and you cure the violation prior to 30 days after
426 your receipt of the notice.
427
428 Termination of your rights under this section does not terminate the
429 licenses of parties who have received copies or rights from you under
430 this License. If your rights have been terminated and not permanently
431 reinstated, you do not qualify to receive new licenses for the same
432 material under section 10.
433
434 9. Acceptance Not Required for Having Copies.
435
436 You are not required to accept this License in order to receive or
437 run a copy of the Program. Ancillary propagation of a covered work
438 occurring solely as a consequence of using peer-to-peer transmission
439 to receive a copy likewise does not require acceptance. However,
440 nothing other than this License grants you permission to propagate or
441 modify any covered work. These actions infringe copyright if you do
442 not accept this License. Therefore, by modifying or propagating a
443 covered work, you indicate your acceptance of this License to do so.
444
445 10. Automatic Licensing of Downstream Recipients.
446
447 Each time you convey a covered work, the recipient automatically
448 receives a license from the original licensors, to run, modify and
449 propagate that work, subject to this License. You are not responsible
450 for enforcing compliance by third parties with this License.
451
452 An "entity transaction" is a transaction transferring control of an
453 organization, or substantially all assets of one, or subdividing an
454 organization, or merging organizations. If propagation of a covered
455 work results from an entity transaction, each party to that
456 transaction who receives a copy of the work also receives whatever
457 licenses to the work the party's predecessor in interest had or could
458 give under the previous paragraph, plus a right to possession of the
459 Corresponding Source of the work from the predecessor in interest, if
460 the predecessor has it or can get it with reasonable efforts.
461
462 You may not impose any further restrictions on the exercise of the
463 rights granted or affirmed under this License. For example, you may
464 not impose a license fee, royalty, or other charge for exercise of
465 rights granted under this License, and you may not initiate litigation
466 (including a cross-claim or counterclaim in a lawsuit) alleging that
467 any patent claim is infringed by making, using, selling, offering for
468 sale, or importing the Program or any portion of it.
469
470 11. Patents.
471
472 A "contributor" is a copyright holder who authorizes use under this
473 License of the Program or a work on which the Program is based. The
474 work thus licensed is called the contributor's "contributor version".
475
476 A contributor's "essential patent claims" are all patent claims
477 owned or controlled by the contributor, whether already acquired or
478 hereafter acquired, that would be infringed by some manner, permitted
479 by this License, of making, using, or selling its contributor version,
480 but do not include claims that would be infringed only as a
481 consequence of further modification of the contributor version. For
482 purposes of this definition, "control" includes the right to grant
483 patent sublicenses in a manner consistent with the requirements of
484 this License.
485
486 Each contributor grants you a non-exclusive, worldwide, royalty-free
487 patent license under the contributor's essential patent claims, to
488 make, use, sell, offer for sale, import and otherwise run, modify and
489 propagate the contents of its contributor version.
490
491 In the following three paragraphs, a "patent license" is any express
492 agreement or commitment, however denominated, not to enforce a patent
493 (such as an express permission to practice a patent or covenant not to
494 sue for patent infringement). To "grant" such a patent license to a
495 party means to make such an agreement or commitment not to enforce a
496 patent against the party.
497
498 If you convey a covered work, knowingly relying on a patent license,
499 and the Corresponding Source of the work is not available for anyone
500 to copy, free of charge and under the terms of this License, through a
501 publicly available network server or other readily accessible means,
502 then you must either (1) cause the Corresponding Source to be so
503 available, or (2) arrange to deprive yourself of the benefit of the
504 patent license for this particular work, or (3) arrange, in a manner
505 consistent with the requirements of this License, to extend the patent
506 license to downstream recipients. "Knowingly relying" means you have
507 actual knowledge that, but for the patent license, your conveying the
508 covered work in a country, or your recipient's use of the covered work
509 in a country, would infringe one or more identifiable patents in that
510 country that you have reason to believe are valid.
511
512 If, pursuant to or in connection with a single transaction or
513 arrangement, you convey, or propagate by procuring conveyance of, a
514 covered work, and grant a patent license to some of the parties
515 receiving the covered work authorizing them to use, propagate, modify
516 or convey a specific copy of the covered work, then the patent license
517 you grant is automatically extended to all recipients of the covered
518 work and works based on it.
519
520 A patent license is "discriminatory" if it does not include within
521 the scope of its coverage, prohibits the exercise of, or is
522 conditioned on the non-exercise of one or more of the rights that are
523 specifically granted under this License. You may not convey a covered
524 work if you are a party to an arrangement with a third party that is
525 in the business of distributing software, under which you make payment
526 to the third party based on the extent of your activity of conveying
527 the work, and under which the third party grants, to any of the
528 parties who would receive the covered work from you, a discriminatory
529 patent license (a) in connection with copies of the covered work
530 conveyed by you (or copies made from those copies), or (b) primarily
531 for and in connection with specific products or compilations that
532 contain the covered work, unless you entered into that arrangement,
533 or that patent license was granted, prior to 28 March 2007.
534
535 Nothing in this License shall be construed as excluding or limiting
536 any implied license or other defenses to infringement that may
537 otherwise be available to you under applicable patent law.
538
539 12. No Surrender of Others' Freedom.
540
541 If conditions are imposed on you (whether by court order, agreement or
542 otherwise) that contradict the conditions of this License, they do not
543 excuse you from the conditions of this License. If you cannot convey a
544 covered work so as to satisfy simultaneously your obligations under this
545 License and any other pertinent obligations, then as a consequence you may
546 not convey it at all. For example, if you agree to terms that obligate you
547 to collect a royalty for further conveying from those to whom you convey
548 the Program, the only way you could satisfy both those terms and this
549 License would be to refrain entirely from conveying the Program.
550
551 13. Use with the GNU Affero General Public License.
552
553 Notwithstanding any other provision of this License, you have
554 permission to link or combine any covered work with a work licensed
555 under version 3 of the GNU Affero General Public License into a single
556 combined work, and to convey the resulting work. The terms of this
557 License will continue to apply to the part which is the covered work,
558 but the special requirements of the GNU Affero General Public License,
559 section 13, concerning interaction through a network will apply to the
560 combination as such.
561
562 14. Revised Versions of this License.
563
564 The Free Software Foundation may publish revised and/or new versions of
565 the GNU General Public License from time to time. Such new versions will
566 be similar in spirit to the present version, but may differ in detail to
567 address new problems or concerns.
568
569 Each version is given a distinguishing version number. If the
570 Program specifies that a certain numbered version of the GNU General
571 Public License "or any later version" applies to it, you have the
572 option of following the terms and conditions either of that numbered
573 version or of any later version published by the Free Software
574 Foundation. If the Program does not specify a version number of the
575 GNU General Public License, you may choose any version ever published
576 by the Free Software Foundation.
577
578 If the Program specifies that a proxy can decide which future
579 versions of the GNU General Public License can be used, that proxy's
580 public statement of acceptance of a version permanently authorizes you
581 to choose that version for the Program.
582
583 Later license versions may give you additional or different
584 permissions. However, no additional obligations are imposed on any
585 author or copyright holder as a result of your choosing to follow a
586 later version.
587
588 15. Disclaimer of Warranty.
589
590 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

620 END OF TERMS AND CONDITIONS
621
622 How to Apply These Terms to Your New Programs
623
624 If you develop a new program, and you want it to be of the greatest
625 possible use to the public, the best way to achieve this is to make it
626 free software which everyone can redistribute and change under these terms.
627
628 To do so, attach the following notices to the program. It is safest
629 to attach them to the start of each source file to most effectively
630 state the exclusion of warranty; and each file should have at least
631 the "copyright" line and a pointer to where the full notice is found.
632
633 <one line to give the program's name and a brief idea of what it does.>
634 Copyright (C) <year> <name of author>
635
636 This program is free software: you can redistribute it and/or modify
637 it under the terms of the GNU General Public License as published by
638 the Free Software Foundation, either version 3 of the License, or
639 (at your option) any later version.
640
641 This program is distributed in the hope that it will be useful,
642 but WITHOUT ANY WARRANTY; without even the implied warranty of
643 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
644 GNU General Public License for more details.
645
646 You should have received a copy of the GNU General Public License
647 along with this program. If not, see <http://www.gnu.org/licenses/>.
648
649 Also add information on how to contact you by electronic and paper mail.
650
651 If the program does terminal interaction, make it output a short
652 notice like this when it starts in an interactive mode:
653
654 <program> Copyright (C) <year> <name of author>
655 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
656 This is free software, and you are welcome to redistribute it
657 under certain conditions; type `show c' for details.
658
659 The hypothetical commands `show w' and `show c' should show the appropriate
660 parts of the General Public License. Of course, your program's commands
661 might be different; for a GUI interface, you would use an "about box".
662
663 You should also get your employer (if you work as a programmer) or school,
664 if any, to sign a "copyright disclaimer" for the program, if necessary.
665 For more information on this, and how to apply and follow the GNU GPL, see
666 <http://www.gnu.org/licenses/>.
667
668 The GNU General Public License does not permit incorporating your program
669 into proprietary programs. If your program is a subroutine library, you
670 may consider it more useful to permit linking proprietary applications with
671 the library. If this is what you want to do, use the GNU Lesser General
672 Public License instead of this License. But first, please read
673 <http://www.gnu.org/philosophy/why-not-lgpl.html>.

9 [This is the first released version of the Lesser GPL. It also counts
10 as the successor of the GNU Library Public License, version 2, hence
11 the version number 2.1.]
12
13 Preamble
14
15 The licenses for most software are designed to take away your
16 freedom to share and change it. By contrast, the GNU General Public
17 Licenses are intended to guarantee your freedom to share and change
18 free software--to make sure the software is free for all its users.
19
20 This license, the Lesser General Public License, applies to some
21 specially designated software packages--typically libraries--of the
22 Free Software Foundation and other authors who decide to use it. You
23 can use it too, but we suggest you first think carefully about whether
24 this license or the ordinary General Public License is the better
25 strategy to use in any particular case, based on the explanations
26 below.
27
28 When we speak of free software, we are referring to freedom of use,
29 not price. Our General Public Licenses are designed to make sure that
30 you have the freedom to distribute copies of free software (and charge
31 for this service if you wish); that you receive source code or can get
32 it if you want it; that you can change the software and use pieces of
33 it in new free programs; and that you are informed that you can do
34 these things.
35
36 To protect your rights, we need to make restrictions that forbid
37 distributors to deny you these rights or to ask you to surrender these
38 rights. These restrictions translate to certain responsibilities for
39 you if you distribute copies of the library or if you modify it.
40
41 For example, if you distribute copies of the library, whether gratis
42 or for a fee, you must give the recipients all the rights that we gave
43 you. You must make sure that they, too, receive or can get the source
44 code. If you link other code with the library, you must provide
45 complete object files to the recipients, so that they can relink them
46 with the library after making changes to the library and recompiling
47 it. And you must show them these terms so they know their rights.
48
49 We protect your rights with a two-step method: (1) we copyright the
50 library, and (2) we offer you this license, which gives you legal
51 permission to copy, distribute and/or modify the library.
52
53 To protect each distributor, we want to make it very clear that
54 there is no warranty for the free library. Also, if the library is
55 modified by someone else and passed on, the recipients should know
56 that what they have is not the original version, so that the original
57 author's reputation will not be affected by problems that might be
58 introduced by others.
59 ^L
60 Finally, software patents pose a constant threat to the existence of
61 any free program. We wish to make sure that a company cannot
62 effectively restrict the users of a free program by obtaining a
63 restrictive license from a patent holder. Therefore, we insist that
64 any patent license obtained for a version of the library must be
65 consistent with the full freedom of use specified in this license.
66
67 Most GNU software, including some libraries, is covered by the
68 ordinary GNU General Public License. This license, the GNU Lesser
69 General Public License, applies to certain designated libraries, and
70 is quite different from the ordinary General Public License. We use
71 this license for certain libraries in order to permit linking those
72 libraries into non-free programs.
73
74 When a program is linked with a library, whether statically or using
75 a shared library, the combination of the two is legally speaking a
76 combined work, a derivative of the original library. The ordinary
77 General Public License therefore permits such linking only if the
78 entire combination fits its criteria of freedom. The Lesser General
79 Public License permits more lax criteria for linking other code with
80 the library.
81
82 We call this license the "Lesser" General Public License because it
83 does Less to protect the user's freedom than the ordinary General
84 Public License. It also provides other free software developers Less
85 of an advantage over competing non-free programs. These disadvantages
86 are the reason we use the ordinary General Public License for many
87 libraries. However, the Lesser license provides advantages in certain
88 special circumstances.
89
90 For example, on rare occasions, there may be a special need to
91 encourage the widest possible use of a certain library, so that it
92 becomes
93 a de-facto standard. To achieve this, non-free programs must be
94 allowed to use the library. A more frequent case is that a free
95 library does the same job as widely used non-free libraries. In this
96 case, there is little to gain by limiting the free library to free
97 software only, so we use the Lesser General Public License.
98
99 In other cases, permission to use a particular library in non-free
100 programs enables a greater number of people to use a large body of
101 free software. For example, permission to use the GNU C Library in
102 non-free programs enables many more people to use the whole GNU
103 operating system, as well as its variant, the GNU/Linux operating
104 system.
105
106 Although the Lesser General Public License is Less protective of the
107 users' freedom, it does ensure that the user of a program that is
108 linked with the Library has the freedom and the wherewithal to run
109 that program using a modified version of the Library.
110
111 The precise terms and conditions for copying, distribution and
112 modification follow. Pay close attention to the difference between a
113 "work based on the library" and a "work that uses the library". The
114 former contains code derived from the library, whereas the latter must
115 be combined with the library in order to run.
116 ^L
117 GNU LESSER GENERAL PUBLIC LICENSE
118 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
119
120 0. This License Agreement applies to any software library or other
121 program which contains a notice placed by the copyright holder or
122 other authorized party saying it may be distributed under the terms of
123 this Lesser General Public License (also called "this License").
124 Each licensee is addressed as "you".
125
126 A "library" means a collection of software functions and/or data
127 prepared so as to be conveniently linked with application programs
128 (which use some of those functions and data) to form executables.
129
130 The "Library", below, refers to any such software library or work
131 which has been distributed under these terms. A "work based on the
132 Library" means either the Library or any derivative work under
133 copyright law: that is to say, a work containing the Library or a
134 portion of it, either verbatim or with modifications and/or translated
135 straightforwardly into another language. (Hereinafter, translation is
136 included without limitation in the term "modification".)
137
138 "Source code" for a work means the preferred form of the work for
139 making modifications to it. For a library, complete source code means
140 all the source code for all modules it contains, plus any associated
141 interface definition files, plus the scripts used to control
142 compilation
143 and installation of the library.
144
145 Activities other than copying, distribution and modification are not
146 covered by this License; they are outside its scope. The act of
147 running a program using the Library is not restricted, and output from
148 such a program is covered only if its contents constitute a work based
149 on the Library (independent of the use of the Library in a tool for
150 writing it). Whether that is true depends on what the Library does
151 and what the program that uses the Library does.
152
153 1. You may copy and distribute verbatim copies of the Library's
154 complete source code as you receive it, in any medium, provided that
155 you conspicuously and appropriately publish on each copy an
156 appropriate copyright notice and disclaimer of warranty; keep intact
157 all the notices that refer to this License and to the absence of any
158 warranty; and distribute a copy of this License along with the
159 Library.
160
161 You may charge a fee for the physical act of transferring a copy,
162 and you may at your option offer warranty protection in exchange for a
163 fee.
164
165 2. You may modify your copy or copies of the Library or any portion
166 of it, thus forming a work based on the Library, and copy and
167 distribute such modifications or work under the terms of Section 1
168 above, provided that you also meet all of these conditions:
169
170 a) The modified work must itself be a software library.
171
172 b) You must cause the files modified to carry prominent notices
173 stating that you changed the files and the date of any change.
174
175 c) You must cause the whole of the work to be licensed at no
176 charge to all third parties under the terms of this License.
177
178 d) If a facility in the modified Library refers to a function or a
179 table of data to be supplied by an application program that uses
180 the facility, other than as an argument passed when the facility
181 is invoked, then you must make a good faith effort to ensure that,
182 in the event an application does not supply such function or
183 table, the facility still operates, and performs whatever part of
184 its purpose remains meaningful.
185
186 (For example, a function in a library to compute square roots has
187 a purpose that is entirely well-defined independent of the
188 application. Therefore, Subsection 2d requires that any
189 application-supplied function or table used by this function must
190 be optional: if the application does not supply it, the square
191 root function must still compute square roots.)
192
193 These requirements apply to the modified work as a whole. If
194 identifiable sections of that work are not derived from the Library,
195 and can be reasonably considered independent and separate works in
196 themselves, then this License, and its terms, do not apply to those
197 sections when you distribute them as separate works. But when you
198 distribute the same sections as part of a whole which is a work based
199 on the Library, the distribution of the whole must be on the terms of
200 this License, whose permissions for other licensees extend to the
201 entire whole, and thus to each and every part regardless of who wrote
202 it.
203
204 Thus, it is not the intent of this section to claim rights or contest
205 your rights to work written entirely by you; rather, the intent is to
206 exercise the right to control the distribution of derivative or
207 collective works based on the Library.
208
209 In addition, mere aggregation of another work not based on the Library
210 with the Library (or with a work based on the Library) on a volume of
211 a storage or distribution medium does not bring the other work under
212 the scope of this License.
213
214 3. You may opt to apply the terms of the ordinary GNU General Public
215 License instead of this License to a given copy of the Library. To do
216 this, you must alter all the notices that refer to this License, so
217 that they refer to the ordinary GNU General Public License, version 2,
218 instead of to this License. (If a newer version than version 2 of the
219 ordinary GNU General Public License has appeared, then you can specify
220 that version instead if you wish.) Do not make any other change in
221 these notices.
222 ^L
223 Once this change is made in a given copy, it is irreversible for
224 that copy, so the ordinary GNU General Public License applies to all
225 subsequent copies and derivative works made from that copy.
226
227 This option is useful when you wish to copy part of the code of
228 the Library into a program that is not a library.
229
230 4. You may copy and distribute the Library (or a portion or
231 derivative of it, under Section 2) in object code or executable form
232 under the terms of Sections 1 and 2 above provided that you accompany
233 it with the complete corresponding machine-readable source code, which
234 must be distributed under the terms of Sections 1 and 2 above on a
235 medium customarily used for software interchange.
236
237 If distribution of object code is made by offering access to copy
238 from a designated place, then offering equivalent access to copy the
239 source code from the same place satisfies the requirement to
240 distribute the source code, even though third parties are not
241 compelled to copy the source along with the object code.
242
243 5. A program that contains no derivative of any portion of the
244 Library, but is designed to work with the Library by being compiled or
245 linked with it, is called a "work that uses the Library". Such a
246 work, in isolation, is not a derivative work of the Library, and
247 therefore falls outside the scope of this License.
248
249 However, linking a "work that uses the Library" with the Library
250 creates an executable that is a derivative of the Library (because it
251 contains portions of the Library), rather than a "work that uses the
252 library". The executable is therefore covered by this License.
253 Section 6 states terms for distribution of such executables.
254
255 When a "work that uses the Library" uses material from a header file
256 that is part of the Library, the object code for the work may be a
257 derivative work of the Library even though the source code is not.
258 Whether this is true is especially significant if the work can be
259 linked without the Library, or if the work is itself a library. The
260 threshold for this to be true is not precisely defined by law.
261
262 If such an object file uses only numerical parameters, data
263 structure layouts and accessors, and small macros and small inline
264 functions (ten lines or less in length), then the use of the object
265 file is unrestricted, regardless of whether it is legally a derivative
266 work. (Executables containing this object code plus portions of the
267 Library will still fall under Section 6.)
268
269 Otherwise, if the work is a derivative of the Library, you may
270 distribute the object code for the work under the terms of Section 6.
271 Any executables containing that work also fall under Section 6,
272 whether or not they are linked directly with the Library itself.
273
274 6. As an exception to the Sections above, you may also combine or
275 link a "work that uses the Library" with the Library to produce a
276 work containing portions of the Library, and distribute that work
277 under terms of your choice, provided that the terms permit
278 modification of the work for the customer's own use and reverse
279 engineering for debugging such modifications.
280
281 You must give prominent notice with each copy of the work that the
282 Library is used in it and that the Library and its use are covered by
283 this License. You must supply a copy of this License. If the work
284 during execution displays copyright notices, you must include the
285 copyright notice for the Library among them, as well as a reference
286 directing the user to the copy of this License. Also, you must do one
287 of these things:
288
289 a) Accompany the work with the complete corresponding
290 machine-readable source code for the Library including whatever
291 changes were used in the work (which must be distributed under
292 Sections 1 and 2 above); and, if the work is an executable linked
293 with the Library, with the complete machine-readable "work that
294 uses the Library", as object code and/or source code, so that the
295 user can modify the Library and then relink to produce a modified
296 executable containing the modified Library. (It is understood
297 that the user who changes the contents of definitions files in the
298 Library will not necessarily be able to recompile the application
299 to use the modified definitions.)
300
301 b) Use a suitable shared library mechanism for linking with the
302 Library. A suitable mechanism is one that (1) uses at run time a
303 copy of the library already present on the user's computer system,
304 rather than copying library functions into the executable, and (2)
305 will operate properly with a modified version of the library, if
306 the user installs one, as long as the modified version is
307 interface-compatible with the version that the work was made with.
308
309 c) Accompany the work with a written offer, valid for at
310 least three years, to give the same user the materials
311 specified in Subsection 6a, above, for a charge no more
312 than the cost of performing this distribution.
313
314 d) If distribution of the work is made by offering access to copy
315 from a designated place, offer equivalent access to copy the above
316 specified materials from the same place.
317
318 e) Verify that the user has already received a copy of these
319 materials or that you have already sent this user a copy.
320
321 For an executable, the required form of the "work that uses the
322 Library" must include any data and utility programs needed for
323 reproducing the executable from it. However, as a special exception,
324 the materials to be distributed need not include anything that is
325 normally distributed (in either source or binary form) with the major
326 components (compiler, kernel, and so on) of the operating system on
327 which the executable runs, unless that component itself accompanies
328 the executable.
329
330 It may happen that this requirement contradicts the license
331 restrictions of other proprietary libraries that do not normally
332 accompany the operating system. Such a contradiction means you cannot
333 use both them and the Library together in an executable that you
334 distribute.
335
336 7. You may place library facilities that are a work based on the
337 Library side-by-side in a single library together with other library
338 facilities not covered by this License, and distribute such a combined
339 library, provided that the separate distribution of the work based on
340 the Library and of the other library facilities is otherwise
341 permitted, and provided that you do these two things:
342
343 a) Accompany the combined library with a copy of the same work
344 based on the Library, uncombined with any other library
345 facilities. This must be distributed under the terms of the
346 Sections above.
347
348 b) Give prominent notice with the combined library of the fact
349 that part of it is a work based on the Library, and explaining
350 where to find the accompanying uncombined form of the same work.
351
352 8. You may not copy, modify, sublicense, link with, or distribute
353 the Library except as expressly provided under this License. Any
354 attempt otherwise to copy, modify, sublicense, link with, or
355 distribute the Library is void, and will automatically terminate your
356 rights under this License. However, parties who have received copies,
357 or rights, from you under this License will not have their licenses
358 terminated so long as such parties remain in full compliance.
359
360 9. You are not required to accept this License, since you have not
361 signed it. However, nothing else grants you permission to modify or
362 distribute the Library or its derivative works. These actions are
363 prohibited by law if you do not accept this License. Therefore, by
364 modifying or distributing the Library (or any work based on the
365 Library), you indicate your acceptance of this License to do so, and
366 all its terms and conditions for copying, distributing or modifying
367 the Library or works based on it.
368
369 10. Each time you redistribute the Library (or any work based on the
370 Library), the recipient automatically receives a license from the
371 original licensor to copy, distribute, link with or modify the Library
372 subject to these terms and conditions. You may not impose any further
373 restrictions on the recipients' exercise of the rights granted herein.
374 You are not responsible for enforcing compliance by third parties with
375 this License.
376
377 11. If, as a consequence of a court judgment or allegation of patent
378 infringement or for any other reason (not limited to patent issues),
379 conditions are imposed on you (whether by court order, agreement or
380 otherwise) that contradict the conditions of this License, they do not
381 excuse you from the conditions of this License. If you cannot
382 distribute so as to satisfy simultaneously your obligations under this
383 License and any other pertinent obligations, then as a consequence you
384 may not distribute the Library at all. For example, if a patent
385 license would not permit royalty-free redistribution of the Library by
386 all those who receive copies directly or indirectly through you, then
387 the only way you could satisfy both it and this License would be to
388 refrain entirely from distribution of the Library.
389
390 If any portion of this section is held invalid or unenforceable under
391 any particular circumstance, the balance of the section is intended to
392 apply, and the section as a whole is intended to apply in other
393 circumstances.
394
395 It is not the purpose of this section to induce you to infringe any
396 patents or other property right claims or to contest validity of any
397 such claims; this section has the sole purpose of protecting the
398 integrity of the free software distribution system which is
399 implemented by public license practices. Many people have made
400 generous contributions to the wide range of software distributed
401 through that system in reliance on consistent application of that
402 system; it is up to the author/donor to decide if he or she is willing
403 to distribute software through any other system and a licensee cannot
404 impose that choice.
405
406 This section is intended to make thoroughly clear what is believed to
407 be a consequence of the rest of this License.
408
409 12. If the distribution and/or use of the Library is restricted in
410 certain countries either by patents or by copyrighted interfaces, the
411 original copyright holder who places the Library under this License
412 may add an explicit geographical distribution limitation excluding those
413 countries, so that distribution is permitted only in or among
414 countries not thus excluded. In such case, this License incorporates
415 the limitation as if written in the body of this License.
416
417 13. The Free Software Foundation may publish revised and/or new
418 versions of the Lesser General Public License from time to time.
419 Such new versions will be similar in spirit to the present version,
420 but may differ in detail to address new problems or concerns.
421
422 Each version is given a distinguishing version number. If the Library
423 specifies a version number of this License which applies to it and
424 "any later version", you have the option of following the terms and
425 conditions either of that version or of any later version published by
426 the Free Software Foundation. If the Library does not specify a
427 license version number, you may choose any version ever published by
428 the Free Software Foundation.
429
430 14. If you wish to incorporate parts of the Library into other free
431 programs whose distribution conditions are incompatible with these,
432 write to the author to ask for permission. For software which is
433 copyrighted by the Free Software Foundation, write to the Free
434 Software Foundation; we sometimes make exceptions for this. Our
435 decision will be guided by the two goals of preserving the free status
436 of all derivatives of our free software and of promoting the sharing
437 and reuse of software generally.
438
439 NO WARRANTY
440
441 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
442 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
443 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
444 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
445 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
446 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
447 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
448 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
449 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
450
451 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
452 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
453 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
454 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
455 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
456 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
457 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
458 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
459 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
460 DAMAGES.

462 END OF TERMS AND CONDITIONS

464 How to Apply These Terms to Your New Libraries
465
466 If you develop a new library, and you want it to be of the greatest
467 possible use to the public, we recommend making it free software that
468 everyone can redistribute and change. You can do so by permitting
469 redistribution under these terms (or, alternatively, under the terms
470 of the ordinary General Public License).
471
472 To apply these terms, attach the following notices to the library.
473 It is safest to attach them to the start of each source file to most
474 effectively convey the exclusion of warranty; and each file should
475 have at least the "copyright" line and a pointer to where the full
476 notice is found.
477
478

480 does.>

482
483 This library is free software; you can redistribute it and/or
484 modify it under the terms of the GNU Lesser General Public
485 License as published by the Free Software Foundation; either
486 version 2 of the License, or (at your option) any later version.
487
488 This library is distributed in the hope that it will be useful,
489 but WITHOUT ANY WARRANTY; without even the implied warranty of
490 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
491 Lesser General Public License for more details.
492
493 You should have received a copy of the GNU Lesser General Public
494 License along with this library; if not, write to the Free Software
495 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
496
497 Also add information on how to contact you by electronic and paper
498 mail.
499
500 You should also get your employer (if you work as a programmer) or
501 your
502 school, if any, to sign a "copyright disclaimer" for the library, if
503 necessary. Here is a sample; alter the names:
504
505 Yoyodyne, Inc., hereby disclaims all copyright interest in the
506 library `Frob' (a library for tweaking knobs) written by James
507 Random Hacker.
